One of the main devices that ensures stable operation of a carburetor engine in all modes is the carburetor. Not so long ago, domestically produced cars were equipped with a fuel supply system using this device. Therefore, almost every owner of a “classic” has to deal with carburetor repair and adjustment, and for this it is not necessary to contact a service center, since the necessary procedures are easy to do with your own hands.

Introduction
Owners of domestic vehicles, such as, for example, the VAZ-2103, quite often try to fix the car with their own hands. Despite the fact that modern service stations are located on almost every corner and by turning to qualified specialists one could avoid wasting one’s own time, many are in no hurry to solve their problems in this way. Some self-taught craftsmen independently carry out such complex operations, which include adjusting the VAZ-2103 carburetor. Of course, in order to do something like this with your own hands, you need not only free time and patience, but also important and useful knowledge regarding the design features of the device in question.
To adjust the VAZ-2103 carburetor, free time, patience and knowledge are required
In the material below, we will consider the principle of the design of the carburetor of the domestic VAZ-2103, its configuration and adjustment.
What problems in the operation of the VAZ-2105 may indicate the need to adjust its carburetor
The design solution of the carburetor on the VAZ-2105 is aimed at ensuring continuous operation of its engine. However, some circumstances can cause the device to malfunction:
- poor quality fuel;
- incorrect operation of the components of the mechanism;
- natural aging of parts, components and materials from which they are made.
The following malfunctions, which many VAZ-2105 owners may encounter, clearly signal that something is wrong with the carburetor. And it needs adjustment or even repair.
- The car, idling, suddenly stalls.
- The next time you press the gas pedal, acceleration does not occur immediately, but with a delay. Over time, isolated situations “enter” the system with a gradual increase in the interval between applying the gas and increasing the speed of the car.
- Intermittent engine operation, which becomes more noticeable in high gears.
- Increased consumption.
- It is difficult to start the engine after a long period of parking.
In all situations, experienced mechanics begin by removing the device to flush, clean, and purge jet clearances. Low-quality gasoline and failure of filters often cause clogging of the holes. Through them, the fuel mixture incorrectly enters the system, causing various problems.
The smell of fuel in the cabin or flooding of spark plugs may indicate that the carburetor of your VAZ-2105 is not working correctly and needs not just cleaning and purging, but adjustment. For beginners, it is better to turn to specialists who will competently perform all types of work. Experienced car owners do the adjustments themselves.
How to set up a carburetor
Before you start adjusting the penny carburetor, you need to make sure that all components that affect the normal functioning of the internal combustion engine are in good condition. Check the spark plugs, the gap between the electrodes, the distributor, the coil, and the high-voltage wires. You can adjust the carburetor on a VAZ 2101 car only at engine operating temperature (85..90 degrees).
But before you start making adjustments, be sure to purchase a repair kit for the VAZ 2101
Moreover, pay attention to the fact that this repair kit matches your carburetor. If Solex is installed, then you do not need to buy a repair kit for DAAZ
Of course, the price of this set is not very high, but if you buy the wrong one, you will have to run around a little, exchanging for the right one. Disconnect the cable that connects the accelerator pedal to the throttle valve drive. The pipe connecting the air filter housing to the breather must also be disconnected.
Make sure that there is no vacuum in the hose connecting the carburetor to the advance angle adjuster on the distributor. Now you need to adjust the quality of the mixture. Screw in the screws one at a time until the engine begins to shake slightly. Now we need to achieve normal and most stable operation. To do this, unscrew the quality screws one by one. Do not make more than one turn. This adjustment is purely by ear, but it is quite possible to normally adjust the carburetor of a penny in this way.
To determine how well the adjustment has been made, open the throttle sharply and then close it immediately. If the speed increases sharply, there are no delays, then the carburetor is adjusted correctly. But the further operation of the VAZ 2101 will show more accurately. Carefully monitor how much gasoline is consumed per hundred kilometers. From time to time, check the condition of the spark plugs; if there is carbon deposits on them, adjust the air supply to the carburetor of the VAZ 2101.
Idle speed adjustment
The idle system in the carburetor is the most unstable. Therefore, it needs to be adjusted from time to time. The idle speed control elements are 2 screws, one of which determines the composition of the mixture, and the second regulates its quantity.
The stroke adjustment must be carried out on a previously warmed-up engine and with adjusted gaps, which are located in the gas distribution mechanism. You should also check that the ignition timing is set correctly.
Step by step steps:
- Using screw 1, you need to set the crankshaft rotation speed to 820-900 min-1 using the stand tachometer.
- Using screw 2, it is necessary to achieve the CO concentration in the exhaust gases without going beyond 0.5-1.2%.
- Use screw 1 to restore the shaft speed to 820-900 min-1.
- Screw 2 needs to restore the CO concentration to 0.5-1.2%.
- To complete, press limit marks (plastic bushings) onto these screws and orient the slots of these bushings relative to the mounting lugs.
Problems that may arise when setting idle speed:
- There is no reaction from the engine to tightening the propeller (during tightening, the engine should gradually slow down and eventually stall). This sometimes happens if there is an excess of gasoline in the idle speed indicator. The reasons may be:
- very large jet XX;
- the solenoid valve or plug is not screwed in properly;
- The seat of the XX jet has a deformation in its structure or the jet itself is damaged.
Ways out of the situation are presented below. So, with the engine running smoothly at idle, remove the wire from the solenoid valve. When this action is performed, the engine will stop immediately. If this is exactly what happened, then most likely the XX jet is too large and does not suit you. The solution here is very easy - purchase and install a smaller one.
- If the engine continues to run, then most likely gasoline does not enter the XX nozzle, but goes by. You need to carry out the following manipulations, namely, unscrew the plug (solenoid valve) and examine your XX jet to see if it is damaged. If deformations are detected, there is no other way but to buy a new carburetor cover. If no deformations were found during your examination, put the jet on the valve, lubricate the O-ring with oil and tighten it with a wrench (tighten without much effort, it is advisable to tighten with a wrench using only one finger).
Choosing a carburetor for the “classic”
If you are a fan of drive and want more than what the standard system gives you, then the DAAZ 21053 carburetor, manufactured under license from the French company Solex, may be suitable for you. This carburetor is the most economical and provides the best dynamics for classic engines, but it is quite difficult to find it on sale; not all sellers know about its existence. It uses a design that is fundamentally different from the designs of previous DAAZ models. A fuel reverse supply system is used here; there is an outlet through which excess gasoline is returned to the tank, this allows you to save about 500-700 grams of fuel per 100 kilometers.
Depending on the model, there may be many auxiliary electronic systems, such as: an idle system controlled by an electro-valve, an automatic choke system and others. But most of them are installed on export models; we mainly have only an idle system with an electric valve. By the way, it can give you a lot of problems, in this carburetor there are very small channels for fuel and air, and they very often become clogged, if they are not cleaned in time, then the first thing that starts to work poorly is the idle system. This carburetor uses about 6-9 liters of fuel during normal driving, while providing the best dynamics of all the units presented above, except for Webers. If you want to get the most out of the engine, but at the same time not bore yourself with unnecessary details of carburetor settings, then feel free to choose it.
Well, I have listed for you all the standard carburetors that are installed on classics without modifications, you just need to remember that if you buy a carburetor, then you need to select it according to the engine size of your car. Even if you get a good carburetor, but it is designed for a different cubic capacity, then with the help of a specialist you can change the jets in it and adjust it to your needs.
But don't think that choosing to install a carburetor ends with this list.
If you want to get even more from your car and have a good carburetor technician or can customize them yourself, then you can turn your attention to two more types of carburetors, Solex 21073 and Solex 21083:
- the first is designed for a volume of 1.7 cubic centimeters (for the Niva engine), it differs from 21053 in that it has larger channels and larger jets. After installing it, you will get even more dynamics, but fuel consumption will be 9-12 liters per 100 km. So if you want a lot of dynamics and at the same time have the money to pay for the extra expense, you can choose it.
- the second (21083) is intended for VAZ 2108-09 cars, and is installed on classic engines only with modifications, because the gas distribution systems of engines 01-07 and 08-09 are different. And if you install the carburetor as is, then at a speed of about 4000 thousand, the speed of the intake air can approach above the sound speed, which is unacceptable, the engine simply will not accelerate any further. If you want to install it, you will have to drill out the diffusers of chambers 1 and 2 to a larger size, and install slightly larger jets. All these alterations are worth doing only if you are a sincere connoisseur of the classics, as they are quite labor-intensive. The price of the alterations is consumption of less than 21,053, increase in dynamics by even more than 21,073.
We can say even more, there are single-chamber and double-chamber carburetors from imported companies, but they are, firstly, expensive, and secondly, they do not always provide better dynamics and economy than those listed above. So it’s up to you to decide what to choose and how to drive.

Adjustment and design of the carburetor on the VAZ 2101
The carburetor on the VAZ 2101 requires periodic tuning and adjustment. Otherwise, the engine will not operate stably at idle or during acceleration. Starting difficulties may also occur. Setting up a carburetor requires some knowledge. However, knowing the technology of how the VAZ 2101 carburetor is adjusted, or as it is popularly called “Kopeyki”, you can perform the entire procedure with your own hands.
Throttle valve adjustment
Adjusting the VAZ-2101 carburetor begins with adjusting the throttle valve. This is a simple procedure. It can be done in three stages. Manually turn the damper control lever counterclockwise. It opens completely.
The distance to the primary chamber is measured. The carburetor design suggests that this figure is 12.5-13.5 mm. If the result is different, you need to bend the rod antennae. Throttle adjustment involves determining the opening value of the throttle valve. It should be 14.5-15.5 mm. Otherwise, you will need to tighten the pneumatic drive rod.
Adjusting the VAZ 2101 carburetor - Do-it-yourself VAZ repair
Adjusting the VAZ 2101 carburetor is a very important procedure, without which any car, and even more so, one as old as a “penny”, will not be able to function normally.
It is important to note that carburetor adjustments have been taught for more than one year, and there is even such a profession as a carburetor technician, but we firmly believe that with a certain package of knowledge and without fear of “getting your hands dirty,” absolutely every car owner can handle it.
It is for this reason that we decided to compile quite detailed instructions for you so that you can save your money and continue to enjoy trips on real domestic classics.
If you are tired of tuning and repairing the carburetor, as well as the solid fuel consumption of your penny, you should pay attention to the eleventh generation Corolla cars at toyota-ua.com/models/new-corolla. The 2013 Toyota Corolla delivers significant fuel economy thanks to fuel injector, which delivers consistent, efficient engine performance and lower emissions.
Adjusting the throttle position
The first step in adjusting the carburetor on a “penny” is to set the correct throttle position. To do this job correctly, you must perform the following simple manipulations:
Step 1: In manual mode, rotate the throttle control lever counterclockwise until the throttle valve is fully open.
Step 2: measure the distance to the primary chamber, it should be between 12.5 and 13.5 millimeters. If this is not the case, correct it by bending the rod tendril.
Step 3: measure the maximum throttle opening, it should be between 14.5 and 15.5 millimeters. If this is not the case, then you should correct it by tightening the pneumatic actuator rod.
Correcting the starting device
At the second stage, adjusting the VAZ 2101 carburetor involves adjusting the starting device. As in the previous case, we will provide step-by-step instructions that will help you complete the task easily and simply.
Step 1: In manual mode, turn the secondary throttle lever counterclockwise until it closes.
Step 2: Check that the tip of the thrust lever is firmly attached to the primary throttle shaft and is located at the very end of the trigger rod. If you find that this is not the case, then you will need to correct its position by bending the rod.
Important! You need to bend the rod very carefully, as too much pressure can break it off.
Adjusting the performance of the pump accelerator
The third stage of adjusting the operation of the carburetor on the VAZ 2101 is to control and debug the pump accelerator.
You need to start working with it by checking its functionality. To do this, you must collect the fuel in a beaker that will be generated in 10 full cycles of operating the throttle control lever.
You should get between 5.25 and 8.75 cubic centimeters of fuel. If this is not the case, then you will need to fully bleed the pump 9-10 times, and then measure again.
If this does not help, then you will have to completely change the fuel pump accelerator.
Setting the correct idle speed for the car engine
Adjusting the VAZ 2101 carburetor at the final stage involves setting the correct engine idle speed. To do this, you must follow these simple steps.
Step 1: Warm up the engine for 10-15 minutes.
Step 2: Stop the engine and close the quality screw and quantity screw all the way.
Step 3: Loosen the quantity screw 3 turns and the quality screw 5 turns.
Step 4: Start the engine and use the speed screw to set the engine speed to 800 rpm.
Step 5: Begin to slowly tighten the quality screw, thereby reducing the richness of the fuel mixture. This must be done until the revolutions begin to drop.
Acceleration pump
Enriches the fuel mixture when the throttle valve is opened sharply, ensuring good vehicle response. When the throttle valve 39 is sharply opened (see Fig. 33), the cam on the valve axis presses lever 1 and acts through the pusher on the diaphragm 48, overcoming the resistance of the return spring. The diaphragm supplies fuel through the channel and injects it through the atomizer 15 into the primary mixing chamber. Part of the fuel is passed through the bypass jet 47 back into the float chamber. The bypass jet is selected in such a way that when the throttle valve is opened smoothly, all the fuel is bypassed into the float chamber. The cam profile allows for dual injection. The second injection coincides with the beginning of the opening of the throttle valve of the secondary chamber.
The sprayer 12 has a marking (for example, 40) indicating the diameter of the sprayer opening (0.40 mm).
We adjust the speed on the VAZ 2101-VAZ 2107
Check out the photo below:
Note! The photo shows the screws that carry out the adjustment. They are located deep in the carburetor throttle body, so the screw under the number “1” is not visible in the image. On some cars, bushings are pressed onto both screws, thanks to which the screws can only be turned half a turn. If the bushings prevent the idle speed screw from turning properly, remove the screws and break the bushing heads. Wipe off the remaining broken bushings and screw the screws in their place.
Gas analyzer to the rescue!
First, start the car and let it warm up to operating temperature of “90-95 ° C”. Afterwards, using a screwdriver, start rotating the screw under the number “2”, rotate it until the crankshaft speed reaches “750-800 min”.
Note! Tightening the screw leads to a decrease in the crankshaft speed, and unscrewing it leads to an increase!
Now smoothly proceed to adjusting the “CO” content in the exhaust gases: turn screw number “1” in the photo above. When tightening the screw, the “CO” in the exhaust gases will gradually decrease, and unscrewing it will increase accordingly.
Note! It is required to regulate the CO content in the exhaust in accordance with GOST today. There is no need to lower “CO” below the norm, otherwise the content of unburned hydrocarbons “CH” may increase sharply. By the way, adjusting screw “1” changes the crankshaft speed.
Finally, turn screw “2”, bringing the crankshaft rotation speed back to normal. Check the amount of CO in the exhaust using the device. Adjust the screws until engine operation and CO emissions into the atmosphere reach normal levels.
Note! After all the manipulations, get into the car, sharply press the gas pedal and release. Make sure that the engine runs smoothly, and when you release the pedal, the car engine should not stall. Is it stalling? – increase the crankshaft speed to “800 rpm” with screw No. 2.
Setting idle speed
The process involves two screws that set the quantity and quality of the mixture. For high-quality settings, having a gas analyzer will not hurt. Before adjusting the carburetor on a VAZ 2106, you need to know about the restrictive plastic bushings that are pressed onto the adjusting screws. These plugs do not allow you to violate the factory settings. If this factor prevents you from setting XX normally, then you should break them out with a slotted screwdriver.
Idle speed control technology:
- With the air damper open, set the crankshaft speed screw to 800-900 rpm.
- Rotate the quality screw to set the maximum engine speed.
- Using the quantity screw, set the speed on the tachometer to 950-1030 rpm.
- Use the quality screw to set the maximum speed again.
- Repeat these operations until the speed of 950-1030 rpm does not coincide with the maximum speed set using the quality screw.
- After the moment of coincidence, return the quality screw to the position where the engine speed was 800-900 rpm.
Purpose of an important node
Many motorists who have no idea how to adjust the carburetor on a VAZ-2103 simply do not understand the principle of operation and design of this device. The function of any carburetor is to mix gasoline and air together. Thanks to this simple device, a special mixture appears in the car at the moment the power unit is activated, transported into the engine cylinders. In fact, how efficiently the vehicle itself operates depends on how well the engine is supplied with gasoline.
Among other components of the device in question, it is worth noting such elements as air and throttle valves, mixing chambers and idle air valve. Of course, these are not all the components of the VAZ-2103 carburetor; in the material below we will consider in detail the operation and principle of setting each individual unit.
The function of the VAZ-2103 carburetor is to mix gasoline and air together
The functionality of any power unit that interacts with a carburetor depends on several important criteria:
- starting and warming up the engine;
- idle devices;
- design responsible for controlling the amount of fuel;
- accelerator pump (how quickly the car can accelerate depends on it);
- the performance of the elements located in the central dosing chamber;
- econostat (located in one of the internal combustion chambers of the engine).
Starting device
Ensures cold engine starting. It consists of an air damper 2 (Fig. 34) above the primary mixing chamber, a three-arm lever 1, a telescopic rod, a throttle valve drive rod 7 and a diaphragm device. Lever 1 is connected by a rod to the manual control button in the cabin under the instrument panel. When the button is pulled, the three-arm lever through rod 7 slightly opens the throttle valve of the primary chamber, and the telescopic rod, by turning the air damper lever, closes the air damper. Rod 3, connected to the air damper lever, moves along the groove of the rod 4 and occupies the extreme left position.
Verifying that the settings are correct
After completing the adjustment, you need to make sure that the carburetor is working optimally. To do this, sharply press the accelerator pedal several times. If the engine picks up speed smoothly and does not stall, then the screws are adjusted correctly. Inexperienced drivers often open the throttle too much, which leads to excessive fuel consumption. Therefore, the quantity screw must be in such a position that the volume of fuel is sufficient for stable operation of the engine at idle.
It is worth noting that the “Weber” carburetors that were previously equipped with “kopecks” are not so easy to adjust. Therefore, with little experience, it is recommended to contact an experienced specialist, since not even all car services are able to properly configure such “rarities”.
Adjusting the carburetor on a VAZ 2101 will not cause difficulties for experienced car owners. For beginners, it is better to do this work with a familiar master, since it is difficult to adjust the screws correctly the first time. By performing such repairs carefully and according to the instructions, you will make the engine run smoothly and reliably.
Repair instructions
As a rule, carburetor adjustment is required after 7500–8000 km. If the car is not used much, then this work should be carried out at least once a year. Before tuning, thoroughly clean the spark plugs, distributor and check the wiring.
Tip: During repairs, new cuffs and jets may be needed; these parts should be purchased in advance.
List of tools and preparatory work
Adjustment does not require much physical strength, the main thing is to do everything accurately and accurately. Preparing the tool:
- set of wrenches;
- flat and Phillips screwdrivers;
- rags;
- latex gloves;
- toothpicks;
- solvent;
- pump or can of compressed air.
The first step is to remove the top cover, float and vacuum valve from the carburetor.
After unscrewing the 4 nuts, remove the top cover of the carburetor and clean the chambers
The internal chambers must be thoroughly cleaned of dust and soot residues. replacing the timing belt on a VAZ 2109. Detailed instructions for bleeding the brakes on a VAZ 2101 yourself + video. In this article you will learn how to properly bleed the brake system of a VAZ. How to properly tighten the timing belt on a VAZ 2108. We clean small holes with air using a spray can or a regular pump. Warm up the engine and set it to the handbrake.
Malfunctions that may precede carburetor adjustment
Adjusting the VAZ-2101 carburetor may be necessary even before the car owner can notice the first signs of a malfunction. For example, unstable operation of the power unit at idle, changes in crankshaft speed, or regular “damping” of the engine are not always problems that arise from the carburetor. The above device can only be blamed when such problems arose out of nowhere, without prerequisites.
For some reason, a failed carburetor or its assembly needs urgent adjustment, even if the changes did not occur too dramatically. As a rule, floating idle speed appears if there is a problem with the solenoid valve.
A motorist who does not know how to adjust the solenoid valve must disconnect the wire supplying this element and apply the “plus” to the valve contact via the battery. If the winding is functioning normally, a soft click will be heard at the moment of connection. At the same time, you need to check the voltage that is on the wire connected to the electric valve. If there is no voltage, the wiring is damaged. Most likely, such a break is located in the section of the wire that goes from the ignition switch to the valve.
Engine malfunctions are not always signs of the need for carburetor adjustment
The need to adjust the carburetor may also arise in a situation where there is a large amount of carbon deposits in the spark plug electrodes. Because of this circumstance, the spark power will not be enough, which will not allow the gasoline-air mixture to ignite. Even the carburetor can affect the carbon deposits accumulated on the electrodes. Performing its function, it transfers a huge amount of mixture to the combustion chambers. In addition, burnout of the intake valve may occur.
First, you need to adjust the fuel level on a VAZ-2101 car. The motorist will have to adjust the position of the float. Problems can appear to a greater extent only at high speeds. Most likely, it is not the carburetor that is to blame, but the fuel supply. In a used VAZ-2101, the fuel pump diaphragm often wears out and the fuel pump rod wears out.
What kind of motor can be installed on a “penny” instead of the standard one?
One of the main types of car tuning is improving the car engine. VAZ 2101 engines are an unplowed field in this sense. Some craftsmen install turbines on them in order to increase power and traction characteristics, others change the crankshaft and bore the cylinders, and still others simply change the engine to a more powerful one.
But here it is important not to overdo it, because the car body is designed for certain loads, exceeding which can seriously harm the entire car.
Among the popular options for replacement, it is worth considering only power units that are similar in design and performance. For a penny, without any problems, you can install a 1.6 or 2.0 liter gasoline engine from the same Fiat Argenta or Polonaise.
The engine from Fiat Argenta can be installed on any classic VAZ without any special modifications
You can try the same engine from Renault Logan or Mitsubishi Galant, if you install them together with a gearbox. But the best option is a power unit from subsequent modifications of VAZs. These could be VAZ 2106, 2107, 2112 and even 2170. The engines from these cars are suitable both in size and in mounting to the gearbox.
General information about the VAZ-2105 carburetor
Listed below are basic information about the carburetors used on the 2105 VAZ model.
- Purpose. To obtain gasoline from the fuel system, mix it with air and transfer it to the engine cylinders.
- Operating modes. There are four of them: preheating, idle load, medium speed, increased power.
- Carburetor type: 2105-1107010 for engines with a power of 1.3 liters. The marking is applied to a special plate that manufacturers attach to various places on the outside of the device. The most popular modifications presented on the Russian market are DAAZ, Ozon, Solex. They are selected according to the volume of the car engine.
- A carburetor is a complex system of interconnected structural parts for various purposes. His main responsibility is to ensure correct fuel consumption and efficient engine operation.
The quality of operation of the 2105 device depends on the modification of the product, the reliability of its components, the brand and quality of gasoline, compliance of the settings with the technical requirements of the operation of the vehicle, sanitary condition, etc. Features of the functioning of carburetors affect the operation of the engine and can change the speed of acceleration and movement car, average gasoline consumption, ignition features.
What engines were the first VAZs equipped with?
“Kopeykas” were equipped with two types of power units: 2101 and . The design of the first was borrowed from the Italian Fiat 124. But this was not a copy, but a real improved version, although the camshaft was modernized. Unlike the Fiat, in which it was located at the bottom of the cylinder head, in the VAZ 2101 the shaft was located at the top. The working volume of this engine was 1.2 liters. It was capable of developing a power of 64 hp. s., which was plenty at that time.
The design of the “penny” engine was borrowed from Fiat
The VAZ 2101 engine differed from its predecessor in volume, which increased to 1.3 liters, and, accordingly, in the size of the cylinders. This did not lead to a significant improvement in power characteristics, however, it was this unit that became the prototype for subsequent modifications, namely 2103 and 2105.

Jets for carburetors of VAZ 2101, VAZ 2103, VAZ 2106, VAZ 2107 cars
During the production of the VAZ 2101, several modifications of carburetors were installed in its system. They differ in the size of the jets, as well as the presence or absence of a vacuum corrector. In early Zhiguli models, a carburetor was installed with an ignition system without a vacuum corrector.
The most common carburetor on the VAZ 2101 car is the DAAZ carburetor model 2101-1107010. A vacuum corrector system is already used here. All modifications of carburetors can be adjusted using a similar scheme. But it is impossible to install a model with a vacuum corrector instead of a design without it, or vice versa. Carburetors of well-known brands DAAZ/Weber, Ozone, Solex are also often used; among non-standard carburetors, I would like to highlight Solex 21073 and Solex 21083.

Classification
Carburetor for VAZ 2101
A large number of classic Zhiguli models use the VAZ 2101 carburetor in various modifications. There are several modifications of manufactured carburetors, which differ not only in the size of the installed jets, but also in the presence or absence of a vacuum corrector system.
The VAZ 2101 carburetor of all modifications is intended only for VAZ 2101 and 21011 engines, where an ignition distributor without a vacuum corrector is installed. On cars of later production systems are installed that are already equipped with vacuum correctors. It should be remembered that the use of carburetors for VAZ 2101, 21011 and 2105 engines without a vacuum regulator cannot be used on other engines and vice versa. The carburetor of the VAZ 2103 and VAZ 2016 is used in a similar way - only on models where there is no vacuum corrector.
Maintenance at home is a rather complex procedure that requires certain skills, knowledge and tools. You can independently adjust the idle speed, replace gaskets, clean jets, fuel channels, and also visually check the operation of the accelerator pump and, if necessary, replace it. But it is advisable to carry out final adjustments and adjustments in a car service center that has diagnostic equipment for checking the level of carbon monoxide in the exhaust gases.
The principle of setting up the VAZ-2103 carburetor
Before you begin repairing the VAZ-2103 carburetor, you should make sure that it is correctly adjusted. If the owner of a domestic vehicle is sure that the VAZ-2103 carburetor urgently needs repair, do not rush to premature conclusions.
Quite often, a simple but competent adjustment is enough for the machine to start functioning as before. Setting up such a unit, by the way, requires the knowledge of the master regarding all calibration data (set values). For carburetor tuning to be successful, it is important to adjust all components of the system. Typically, such actions should begin with external control components. You should make sure that the throttle valves are working properly: if the gas pedal is not under pressure, they should be closed. As soon as the gas pedal is pressed, the dampers should open as smoothly as possible (not jerkily). The next step, which involves correctly setting up the VAZ-2103 carburetor, should be checking the air damper. If the drive is recessed, the structural element being tested must be vertical so that the passage leading to the throttle valve does not block.
Carburetor tuning begins with checking external control components
The accelerator pump deserves no less attention. Its functionality helps to detect sudden pedal input. The condition of the pneumatic drive diaphragm should also be determined. Only after the motorist is confident in the normal operation of the elements (after an external check), it will be necessary to spend some time cleaning the jets and sprayers. First of all, you should get rid of the cover of the device being adjusted, then, using a pump, free the float chamber from various sediments. If there is heavily hardened sediment, you can resort to a metal or wood spatula.
Proper adjustment and cleaning of the carburetor should include the absence of any rags that could clog the jet. As a result, the jets and channels will have to be flushed with clean fuel and purged with air. In order to make sure that all components are completely clean, you need to dismantle them before flushing all the channels. It is important to monitor the order in which the jets will be removed, since subsequent incorrect installation will lead to failure of the power unit. All openings can be freed from harmful accumulations with wire.
It is necessary to completely clean all components: dismantle them and wash all channels
Strainer performance
Adjusting the VAZ-2103 carburetor requires checking the strainer. This element is responsible for the cleanliness of the fuel that enters directly into the float chamber. To clean it, you will have to remove the plug and filter, then free the mesh from any unpleasant stuck particles and blow out the filter itself so that air flows in the direction opposite to the movement of fuel. In this case, any mechanical impact should be avoided.
Before you return the element to be cleaned to its place, you will have to make sure that the fuel nozzle is functioning well. If necessary, it can be blown out. Typically, the float chamber should be drained of gasoline and its needle valve should be open. Before the strainer returns to its rightful location, you need to check the sealing gasket, which can prevent fuel from leaking.
Adjusting the VAZ-2103 carburetor is not complete without cleaning the strainer
Checking the functionality of the float chamber
If you need to adjust the VAZ-2103 carburetor, you will have to pay some attention to the float chamber. If the owner of a vehicle notices increased gas consumption, most likely the reason will be hidden in the too high level of fuel that is in the system being tested. If a completely opposite malfunction is noticed (lack of gasoline), you should check the level of gasoline in the float chamber and the functioning of its needle valve.
First of all, you should get rid of the carburetor cover and, after it is in a horizontal position, adjust the gap that will be formed between the floats and the place where the device being removed will be attached to its base (the distance should not exceed 6.5 mm ). This is exactly the gap that should exist at the maximum possible level of gasoline in the float chamber. To adjust the system, you need to use the float tongue. After this, it is important to check the functionality of the needle valve by removing the float axes and dismantling the valve itself. Both elements must not have mechanical damage.
Float chamber of the VAZ-2103 carburetor
After the adjusting element of the system is installed in place, you should use a bulb to ensure that gasoline flows through the filter. The driver's task is to move freely through the needle valve. The floats should be in place, then it is important to re-pump the gasoline to make sure that there are no leaks anywhere. The result of the work should be installing the cover and checking the gasket (located in the middle between the structure and its cover). The latter must be positioned in such a way that it cannot interfere with blocking the channel and at the same time is located in the mounting holes. The lid should be tightened so that there is no overtightening (there should be no deformation). Otherwise, a deformed part of the system will cause air leaks or gasoline leakage.
It is worth noting that adjusting the VAZ-2103 carburetor is advisable only after warming up the engine and pressing the choke button.
Setting up the starter
The starting system can be configured both with the unit removed and while it is in the car.
Adjustment of the VAZ-2103 carburetor will not be complete if the motorist forgets to adjust the starting system. It is worth noting that a similar procedure can be performed both on a previously removed unit, and directly while it is in the car. If the car owner decides to adjust the starting device without removing the carburetor, he will first have to take care of dismantling the air filter, activating the power unit and slightly raising the choke. As a rule, engine speed should not fall below 3200 per minute.
As soon as the above recommendations are completed, it will be necessary to forcibly raise the air damper (at least by a third). Thanks to this manipulation, the number of revolutions should decrease by 300 units.
The clearance of the VAZ-2103 carburetor should be about 5.5 mm
There are times when such actions are not enough. The driver will have to adjust the speed using the thrust from the pneumatic drive by adjusting the length of the thrust. Adjusting the same structural element on a removed carburetor requires adjusting the distance between the opposite sides of the air damper.
If you are thinking about how to adjust the carburetor on a VAZ-2103, you should not forget about the need to take into account the gap (it should be about 5.5 mm). In view of this circumstance, you need to remove the starting unit tube and use a thin screwdriver to turn the adjusting element of the structure. If you start tightening this screw, the gap will gradually become smaller, otherwise it will become larger. If a motorist independently adjusts the carburetor of the domestic VAZ-2103, he must control the gap that remains between the throttle valve and the diffuser. This gap should not exceed 0.8 mm.
Idling of the device
If the idle speed is set correctly, the number of revolutions will not fluctuate up and down.
Often people who are interested in adjusting the VAZ-2103 carburetor mean by performing the process only adjusting the idle speed. Before you begin this procedure, you need to activate and slightly warm up the power unit (it should reach a temperature of 90 °C). As a rule, adjusting the idle speed of the device in question is impossible without the participation of two screws (quantity, as well as composition of the combustible mixture). One of the screws must be closed with a plug, after which the motor must be activated. Using the screw responsible for the amount of mixture, you should increase the engine speed to 1000 units. And use the mixture composition screw to reduce the adjustable value by 200 units. If configured correctly, the motor will function stably, vibrations should not appear, and the number of revolutions should not vary up and down.

| Author: Vlad (Tolyatti) Crimea B25 (178.45.168.—) Date: 05-03-12 02:27 A little off topic from boats. The carburetor on my car was completely screwed up. Engine 2101 1200 cm3. It was 2105. DAAZ. I have a 2107-1107010-20 that has never been used, also a DAAZ. There is from 21083, in principle, still alive. Only the landing plane was curved. I spent the whole evening leveling it yesterday, I think it was level. Tell me what is better to put. And what pitfalls might there be (except for connecting gas drives, choke, fuel hoses on 2183) I read all sorts of auto forums. They write who does what. |
| Author: Anatoliipif (2.93.163.—) Date: 05-03-12 02:33 Hello. VAZ 21083 will do. Drive from NIVA. Problems in winter - until it warms up, it won’t run. Good luck. Anatoly. |
| Author: Oleg 1974 (—.broadband.corbina.ru) Date: 05-03-12 03:54 Hello everyone! Better put 2107, believe me, this is the best option. The 21083 carburetor sucks, and for the classics you need to install different jets, redo the rods, etc. And 2107 will fit without problems, just don’t touch anything inside, the jets should remain as they are. I once made a living by repairing carburetors for quite a long time, so trust my experience. |

The difference is in the location of the float chamber. If you put carb 2108 on 2101, then the level in the float chamber will change when driving uphill and downhill.... |
| Author: Bubble with PDA (—.cust.tele2.ru) Date: 05-03-12 04:51 But the nivovods from 21073 don’t know that their level is changing))). And the Solex 21051 was the export five. For the vehicle: put 21083, rods from Niva 21213. Be sure to connect the heating element of the primary chamber to the hose coming from the manifold - without it it’s bad. And don’t listen to anyone - Solex is better than Ozone. |
| Author: Bubble with PDA (—.cust.tele2.ru) Date: 05-03-12 04:54 Choke cable: you can stick a new wire (from 8) into the old shell, because staff is not enough. |
| Author: Maslov (—.opera-mini.net) Date: 05-03-12 05:36 When I bought a VAZ 2001 11 years ago, I installed contactless ignition and a V8 carburetor at 1100. The positive thing that happened was that it started well in winter and straightaway. After sitting in the garage for a couple of weeks, since I rarely drove for the last three years, I came, pumped up the gas, pressed the gas pedal 15 times and it started. I could start an argument. The carburetor did not fill the spark plugs. Somehow I tried to start the 7 in this way, it wouldn’t start, I had to pull the choke and not accelerate at all. Consumption at first (2 years) was 7.2 liters. The bad news was that the idle jet was constantly clogged. In 9 years I changed three jets. And indeed, during a long descent, when braking at the bottom, it stalled. So I sold it last year. In stores they sell a kit for installing from eight to classic. |

What do 21073 and 21051 have to do with it. These carbs were designed for a longitudinal engine arrangement, unlike the figure-eight carb. Carbs 21073 and 21083 differ, among other things, in the float chamber rotated 90 degrees. |
| Author: s494 (—.broadband.corbina.ru) Date: 03/05/12 05:55 Since 1994, I know that eight-wheel carbs are installed on classics and they drive happily, without being driven by how the float chamber is located. If we assume that the level changes in such a way that it is noticeable for the operation of the engine, then a classic car with its original carb should stall in turns due to overflow or lack of fuel... well, this is so insignificant, because you yourself understand, why argue about it... |
| Author: lednic606 (85.26.164.—) Date: 05-03-12 06:37 Another “note” from experience... Solex is very sensitive to dirt in gasoline, be sure to install 2 fuel filters in a row, “troubles” will disappear. |
