Today on the roads you can often find cars that are 20 or even 30 years old. These are mainly classic VAZ models. The owners of these old cars do their best to keep them alive and strive for optimal performance. The owners of old Zhiguli cars want to improve the dynamics of the car and reduce fuel consumption. This can be done, but it all depends on the carburetor. Let's look at which carburetor is better to install on the VAZ-2106 to get the result. This task is quite feasible, despite the fact that the driver can replace the device and adjust it independently. If you look at the reviews of drivers who replaced the standard carburetor, the effect is quite noticeable.
A brief history of carburetors for VAZ
On the first classic VAZ models, which were an improved Italian Fiat, devices manufactured by the Dmitrov Automotive Aggregate Plant were installed in the power supply system in conjunction with the motors. For the production of these carburetors, a license was purchased from the French. These mechanisms were assigned the index DAAZ-2106 for the VAZ “Six” model.
Until now, such carburetors are popularly called “DAAZ” and “Weber”. Many car owners still actively use them. The use of these mechanisms gives good dynamic characteristics. These carburetors have a simple design without unnecessary design features. But “Webers” have one very significant drawback - they have huge appetites. These models have not been produced for a long time, since along with the VAZ-2105 model, all other Zhigulis were equipped with Ozon products. Below we will talk about it in more detail.
Installing an additional pump
The disadvantage of the first front-wheel drive VAZ cars was the poor performance of the interior heater. Until the engine warms up to operating temperature, the cabin is cold. This is due to the design of the small circulation circuit, into which coolant enters in small quantities. The problem is solved by installing an additional electric pump from GAZelle.
An additional electric pump is installed in the stove pipeline
To install an electric pump, you must purchase:
- four-pin relay;
- multi-core wires and a two-pin connector;
- fuse socket;
- hoses and clamps for connection to the cooling system;
- electric pump from a GAZelle car.
The pump is placed on a homemade bracket, screwed to one of the bolts on the mounting flange of the gearbox. The antifreeze is first drained and the thermostat is removed, which will interfere with the installation of an additional pump. This is especially true for the injection model VAZ 21099.
To turn on the pump, a small circuit with a relay is assembled
The insertion is made into the return pipe coming from the cabin heater. In this case, the electric pump will create a vacuum in the heater radiator. To turn on the pump together with the ignition and from a separate button, a simple electrical circuit is assembled. A relay with a fuse is placed in the cabin under the dashboard, and any free button is selected as a switch.

Checking the functionality and replacing the water pump on a VAZ 2108–099 is quite simple. Don't forget about preventive measures. You should periodically check the technical condition and lubrication of the pump, and also change the coolant in a timely manner. Under these conditions, the pump will last as long as possible.
Additional electric pump for “nine”
Now the cold weather has arrived and the owner of the VAZ 2109, living in Russia, will again have to face the problem of the stove. Indeed, either the domestic manufacturer initially did not take care of its normal functioning, or this car should have such a system, but the VAZ 2109 with an electric pump, which is installed independently, is more suitable in winter in our country. On a VAZ 2109, installing an electric pump will not take much time and it is enough to know the basic algorithm for carrying out the operation, which will be discussed in our article.
Why and where to install an electric pump on a VAZ 2109
It is clear that no owner wants to freeze in his car all winter. And passengers are unlikely to want to sit in a kind of “refrigerator”, where instead of warming up, you freeze completely. The standard stove of this car, of course, warms, but it does it reluctantly and as if on debt. It's all about its low efficiency, especially at idle, when you're stuck, for example, in traffic jams. Installing an additional electric pump, in this case, solves the problem immediately. In fact, there are many ways to make the interior of your “nine”, but modifying the car’s cooling system by installing an electric pump is the most rational solution.
"Ozone" and its problems
Sometimes the pneumatic drive of the damper on the secondary chamber refuses to work normally.
Troubles also arise with a worn out diaphragm in the forced idle economizer system. If for some reason dirt gets into the mechanism or the adjustments are broken, then the second chamber may not open at all, or it may open, but with a serious delay. This leads to a significant decrease in dynamics. Power is lost, the maximum speed of the car decreases, the engine is unstable at high and medium speeds. Despite all this, the DAAZ-1107010 “Ozone” carburetor produces good dynamic characteristics with a fuel consumption of about seven liters per 100 kilometers. Naturally, the device must be constantly monitored and maintained. To avoid contaminating the internal chambers, it is recommended to periodically clean them. A special carburetor cleaner is used. This chemical is sold in aerosol cans.
Preparing to modernize the engine power system
In order to install two carburetors, it is recommended to initially drain the antifreeze through the fuel heater. After this, it is necessary to dismantle part of the fuel system. To remove the intake manifold, you need to unscrew the five bolts that secure it.
Connecting the carburetor to the manifold is not done on the car. This type of work is carried out in good lighting. Having connected the carburetors one by one to the intake manifolds of the Oka, you need to open both chambers and check the condition of the joint. It is strictly forbidden to allow the edges of the collector to protrude above the joint. The air-fuel mixture will swirl at the junction at high speed and the engine will starve.
Fitting intake manifolds
To eliminate protruding edges, use a metal cutter inserted into a screwdriver or drill. The transition between parts should be as smooth as possible. For better results, you can use sandpaper or special sanding pastes.
Installation of a polished engine power system
During a visual inspection, it is possible to detect sagging and casting defects in both the carburetor and the manifold. A car owner who independently installed and tuned the fuel system knows about the need for modifications, but a newbie may be surprised by the protruding pins inside the manifold. This creates strong resistance to air flow, which significantly reduces the effect of installing two carburetors.
"Solex"
These mechanisms are no less popular. DAAZ-21053 is especially popular. It is also manufactured under license. This carburetor has good dynamic characteristics and is also economical. This is a good solution if you need a carburetor for the “Six”. The design of the Solex is fundamentally different from all previous devices from the Dmitrov Automotive Unit, equipped with a fuel return supply system.
With this solution, gasoline can be returned to the car's gas tank. By using a reverse fuel supply system, it is possible to save up to 400-800 grams of fuel per hundred kilometers. Some versions of Solex can be supplemented with auxiliary electronic systems. Among them is an idle system with the ability to adjust using an electric valve. Also found on export models. In the CIS countries, a model with an electric idle air valve was widespread. This two-chamber carburetor turned out to be quite difficult to operate.
The channels are made narrow and often clogged. If the device is not maintained, then the idle system begins to malfunction first, and then all other components. In terms of fuel consumption, the Solex on the VAZ-2106 consumed from 6 to 10 liters when driving in quiet mode. In terms of dynamic characteristics, the unit is second only to the early Weber. If you do preventive carburetor repairs in a timely manner, Solex will not cause any special problems.
Procedure
Remove the old carburetor and manifold and set it aside. Now comes the responsible part. We put both carburetors on the manifolds and open the dampers. You need to look inside and see if the edges of the collector are sticking out. If you chose Solex, then there shouldn’t be such a problem, but it wouldn’t hurt to check. But Weber has exactly the same problem.
We take a drill, load the cutter and grind the edges. Every time you need to try on the carburetor and check it. However, the work is not difficult, but it requires patience and accuracy.
It is advisable to remove the cylinder head, but it can be done without removing it, it just won’t be very convenient - you need to fit the manifolds to the block and make the necessary slots for the threads. It's not difficult either. Everything is customized in place. The central fastener can be made from 4 mm sheet steel.
We install the manifolds on the cylinder head and connect the heating with the vacuum brake booster. If you have 2101, then these holes can be plugged.
If the carburetors are new, then there should be no problems, if not, then we take them to the carburetor for a rebuild and the same adjustment. To do this, the quality and quantity screws must be unscrewed at the same speed. The next stage is merging the gas and choke pedals. With Solex, usually there are no problems - you only need a cable, but Weber will be a creative process for you. The main thing is synchronicity of work.
How to choose a carburetor and what to install on a VAZ-2106?
Those who like to make improvements to classic models from AvtoVAZ and simply owners who want to improve the performance characteristics of the car most often choose Solex. Models used are DAAZ-21083. Installing them on classic models is impossible without significant modifications.
When thinking about which carburetor is best to install on a VAZ-2106, you need to take into account the engine size. For 1.3-liter units, the DAAZ-2018 option is perfect. For engines with a volume of 1.6 liters, the best choice is DAAZ-21083. The differences between these two models are in the cross-sectional diameter of the diffusers, as well as in the sizes of the fuel and air jets. If you install this carburetor as it is, then at speeds close to 4 thousand, the air emission speed can reach supersonic, which is not acceptable. But this will not affect acceleration in any way. It is necessary to enlarge the diffusers on the first and second chambers and install other jets. After this, fuel consumption will be the same as on 21053, and the dynamics will be better than on 21073. For VAZ-2106 cars, the price of such a carburetor will be about five thousand rubles.
Classic tuning
VAZ 21093 carburetor tuning
To tune a Solex carburetor, you need to carry out the following operations:
- Remove the carburetor itself from the car;
- It is good to clean it from dirt;
- Remove the jets and throttle valves (this is done to bore the diffusers);
- Both chambers must be enlarged in size using a special machine;
- Grind the carburetor to reduce incoming air resistance;
- We select the ones needed for the now modernized carburetor.
Selection of jets
VAZ 21093 carburetor tuning
Selecting jets is the most difficult process. They must be selected taking into account not only coincidence, but also high accuracy. Thus, the VJ must be selected so as to allow a certain amount of air to pass through, which would be equal to the amount of fuel passed through the TJ. Otherwise, the fuel mixture will not be properly balanced, which will inevitably lead to poor acceleration and other problems. In addition, the jets must be properly balanced. This issue must be approached with all responsibility, understanding that instability of the fuel level will lead to a lean mixture.
Carburetor jets
Note. As you know, the ideal level is 1 mm. Other levels lead to malfunctions and loss of power.
In the process of tuning the carburetor, it is also recommended by experts to install a rubber shut-off needle, which ensures a more reliable level during heavy loads. In addition, such a needle is durable and can eliminate freezes when the accelerator pedal is pressed sharply.

Features of the installation DAAZ-2108, -21083
To install any of these models on the “Classic”, it is necessary to prepare a new set of gaskets, hoses for the carburetor heating system, a tee for connecting to the fuel system, a valve and rods for the accelerator. To get the maximum result from this procedure, it is advisable to replace the ignition. It is better to install a more technologically advanced, electronic one. Contact ignition is a thing of the past. The system is very unreliable and often causes operational problems. The installation of contactless electronic ignition is one of the most useful improvements for domestic VAZs, in particular for the Six.

Other options
But don’t think that this is all that is suitable for “Classics”. If you think about which carburetor is better to install on a VAZ-2106, then you also remember the Solex-21073. It is designed for 1.7 liter engines - from 21053 it is distinguished by larger channels and enlarged jets.
After installing it, you can get even more dynamics, and the fuel consumption will be 9-12 liters. And if you are not afraid of the consumption and rare preventative repairs of the Solex carburetor, then you can opt for it.
Preparing tools and devices
If you intend to thoroughly clean the carburetor of your V8, then you will not be able to do it without a compressor. To blow out accumulated dirt from the channels, it is necessary to supply air at a pressure of at least 6 bar. The remaining tools are common ones found in every garage:
- 2 screwdrivers - Phillips and thin with a narrow flat slot;
- a set of small open-end wrenches - 8, 10, 13 mm;
- round nose pliers;
- rubber bulb (syringe);
- 2-3 wooden toothpicks;
- rags.
Compressor for carburetor purging
Liquids for cleaning carburetor channels
A special product sold in aerosol cans (for example, from the ABRO brand) is excellent for cleaning channels. Do not use acetone or inorganic solvents, which corrode plastic parts, for cleaning. Buy new paper gaskets for DAAZ 2108 carburetors in advance (they will also fit the “nine”). You cannot buy or change jets, since the standard ones are designed for the entire service life of the machine, and fakes with large holes for fuel are often sold in repair kits.
Bottom line
Of course, these are not all carburetor models that can be installed specifically on the VAZ-2106 and other classic Zhiguli cars. There are a lot of Chinese devices, as well as devices from European and American manufacturers. Both single- and double-chamber models are available for sale. But they are expensive and do not always guarantee high dynamic performance and efficiency. You will only get one of the two. Therefore, the question of which carburetor is better to install on a VAZ-2106 can be answered this way: it is best to install a domestic device, one of the above. Reviews from motorists recommend installing “Ozone”. It is one of those that, with low fuel consumption, produces maximum dynamics for a car.
Idle speed adjustment
The second setting of the VAZ-2109 carburetor is idle speed, it can be partial or full. The first is for minor speed adjustments, the second is for adjusting the amount of air (setting CO emissions in the exhaust gases).
Partial adjustment is performed using the air-fuel mixture “amount” screw. This screw sets the opening angle of the throttle valves, which ensures that the air-fuel mixture enters the cylinders when the accelerator pedal is released. The “quantity” screw rests on the throttle valve control lever and when screwed in, it pushes the lever, causing the valves to open slightly.
Partial idle adjustment is performed with a warm engine and creating a load on the vehicle's on-board network by turning on the high beam headlights and the interior heater at full power. The adjustment is carried out with the engine running by screwing in/unscrewing the “quantity” screw until the optimal idle speed is established, which for the VAZ-2109 is 800-900 rpm (this can be tracked using a standard or plug-in tachometer).
If it is not possible to set the required speed or the motor operates unstably at it, a complete adjustment is made, which is made by two screws - “quantity” and “quality”.
The algorithm for this adjustment consists of the following stages:
- Warm up the engine and then turn it off;
- We find the quality screw (it may be closed with a plug that will have to be removed), screw it in until it stops, and then unscrew it 3-4 full turns;
- We start the engine, turn on electrical consumers (lighting and stove) to create a load in the on-board network;
- By rotating the “quantity” screw, we achieve 700-800 rpm on the tachometer;
- By turning the “quality” screw, we set the maximum possible speed (they will increase to a certain level, and then stop. The moment the speed increase stops is considered the maximum);
- We set the “quantity” screw to 900 rpm;
- Using the “quality” screw we lower them to 800 rpm;
- We slowly tighten the “quality” screw until interruptions appear in the operation of the power plant, after which we unscrew it back 1 turn;
- We adjust the speed with the “quantity” screw, bringing it to a normal value - 800-900 rpm;
After the adjustment operations, we check that they were carried out correctly. This is done by sharply pressing the gas pedal and then quickly releasing it. With a properly configured carburetor, the engine should respond quickly to pressure, without any failures or hesitations. And after releasing the pedal, the speed will drop to the idle level, without sags or instability of the engine.
Solution found
Installing two carburetors on a “classic” at the same time will solve this problem - fuel will be supplied more evenly and of the same saturation. The engine becomes more powerful and torque increases.
For self-installation you must have:
- wrenches of various diameters;
- pliers;
- drill;
- Bulgarian;
- vice;
- 2 collectors from Oka;
- 2 carburetors of the same model.
Plus, various little things are needed: gasoline tees, hoses, coolant such as antifreeze.
What is the difference between Solex 73 and 83?
Review and DIFFERENCE! The Solex 21073 carburetor differs from others in its large channels and jets. Installing this model on other VAZ cars with a carburetor allows you to achieve an increase in dynamics, but fuel consumption rises to 9-12 liters per hundred.
