In-place cleaning of the Solex carburetor of VAZ 2108, 2109, 21099 cars with carburetor cleaner aerosol

Contamination of the carburetor on a VAZ 2109 entails a fairly large number of problems. The functionality of the engine is impaired and this is manifested in the following phenomena:

• Idling is unstable;
• Power figures are falling;
• Exhaust gases become more toxic;
• Fuel consumption is increasing;
• When overclocking, so-called dips occur.

Often the reason lies in the air filter not being replaced on time, due to which not enough air is supplied and the quality of the mixture deteriorates. The reason may also be low-grade fuel, which many drivers fill their cars with in order to save money. Nothing good will come of this, let's tell you right away.

There are two preventive, one might say temporary, measures. Plus a radical solution to the problem, which consists of disassembling and cleaning the carburetor.

First, let's talk about preventive ones - liquids and aerosols.

Liquid for filling into the tank

Not everyone knows how to clean the carburetor on a VAZ 2109. We recommend contacting the automotive chemicals department, which sells a large number of liquid preparations for cleaning the carburetor. Typically the volume is up to 150 milliliters, which must be poured into the tank before refueling and this fuel must be completely used until the reserve light comes on.

According to the manufacturer, such measures will allow:

• Remove dirt and deposits;
• Improve the quality of engine starting;
• Reduce exhaust toxicity;
• Reduce fuel consumption;
• Improve engine responsiveness.

We recommend paying attention to the company Hi-Gear, which has proven itself in this area and offers truly high-quality liquid. Such preparations are used once every 3-15 thousand kilometers, depending on the operation and quality of the fuel being poured.

Settings

1. Remove the minus terminal from the battery and the air filter.
2. Slightly open the bolt that secures the linkage to the choke lever.
3. Turn the air damper lever until it is completely open.
4. In the cabin on the instrument panel there is an air damper drive lever - press it all the way.
5. Pull the rod all the way out and tighten the bolt that secures the rod to the air mixture lever.
6. Pull the air damper control lever on the instrument panel all the way. If the air damper does not close completely after this, then slightly open the bolt securing the traction cover and, moving the cover, completely close the throttle damper. The bolt can now be tightened.
7. Place the minus terminal and filter in place.

Aerosols

It is convenient to work with them, since the aerosol comes out under pressure and additionally clears blockages with a flow of air with the mixture. Sprayers contain propane, acetone and a number of other dangerous components. Therefore, avoid getting them in your eyes and hands. They catch fire easily and can only be extinguished with carbon dioxide fire extinguishers.

Aerosol Abro for carburetor cleaning

Aerosols do an excellent job, but they cannot clean the float chamber.

The cleaning process is the same for all cars:

1. Remove the air filter;
2. Spray cleaner through the tubes outside and inside;
3. After 3 minutes, start the engine at high speed and spray the product intermittently for 2 minutes.

This process will take you a maximum of 15 minutes.

As for manufacturers, today the following brands are in deserved demand: Abro, Hi-Gear, Mannol, Gunk, STP, Turtle Wax, Wurth.

Pros and cons

Taking into account the characteristics of the engine, in particular the small volume of 1.3 liters, immediately after launch into production the following shortcomings were revealed:

• leaks through the block cover gasket - the error has not been corrected;
• Solex carburetor - required frequent adjustment of the idle modes;
• pump - intensive wear of polymer blades.

Since the 2108 engine was the first with a transverse arrangement under the hood of a car, the default exhaust manifold changed its design in comparison with previous generations of AvtoVAZ internal combustion engines. However, the intake manifold remained the same.

Removing and cleaning the carburetor

Only a complete cleaning of the VAZ 2109 carburetor will give the result that you need. Liquids and aerosols provide a partial effect and serve as means of prevention. They are effective in their work, but you should not rely on such preparations to properly clean the carburetor.

Idle speed adjustment

After installing the carburetor on the VAZ-2107 engine, adjust the idle speed. This is done with the “quality” and “quantity” screws. The adjustment technology is as follows:

• We set the screws to the initial position, screwing them in until they stop, and then unscrewing them a certain number of turns (for a “quality” screw - 2-3 turns, and for a “quantity” screw - 3-4);
• We start the engine and warm it up to operating temperature (85 degrees);
• With the engine running, rotate the “quality” screw to set the maximum crankshaft speed at idle (without pressing the gas pedal);

• By rotating the “quantitative” screw, we further increase the speed as much as possible (it will not increase much);

• By rotating the “quality” screw in different directions, we check whether the highest speed is set (they should not increase);
• By tightening the “quality” screw, we lower the speed to the level of 800-900 rpm;

After the adjustment, we check that it was carried out correctly. To do this, sharply increase the speed with the gas pedal and release the accelerator. If the adjustment is done correctly, there will be no dips when the throttle valves are opened sharply, and the speed increase should be fast. After releasing the pedal, the speed will drop to the idle level (800-900 rpm), the power plant should not stall.

Materials and equipment

The internal surfaces of carburetor chambers are well cleaned with acetone. You can also use diesel fuel, or buy a special aerosol. The instructions will indicate how many minutes the composition is left to sit before washing it off. Having a can of compressed air won't hurt either.

Do not attempt to clean the jets using wire, fishing line or burnt matches. Compressed air, liquid agents and aerosol are what professionals use in practice.

Typically, carburetor cleaning composition is supplied in the form of an aerosol. The product is sprayed, left for several minutes and washed off with gasoline. The word “washing”, moreover, may mean starting the engine. This means that assembly will need to be done in 1-2 minutes. We will leave the choice to the owner.

Only a soft cloth, such as flannel or rags, is suitable for cleaning aluminum. And the use of any fabrics with pile is strictly prohibited. The fact is that the lint will in any case remain in the inside of the carburetor. It will then enter the combustion chamber.

There is a huge selection of products on the market that help you clean the carburetor yourself. But most of the chemical compounds offered even by well-known brands are made on the basis of acetone.

Recommended Method

Level control technology includes a number of stages:

1. We dismantle the housing of the air filter element. To do this, unscrew the fastening nut of the housing cover, unclip the latches, remove the cover, take out the filter and tighten the 4 nuts that secure the housing to the carburetor.

2. Raise the body and disconnect the rubber pipes. We move the body to the side.

3. Loosen the clamps securing the fuel pipes going to the carburetor and disconnect them.
4. Remove the wire suitable for the idle speed solenoid valve;
5. Disconnect the drive cable of the air damper (the “choke” handle);
6. Unscrew the 5 screws securing the carburetor cover;

7. Having removed the cover, we immediately determine the fuel level in the chambers by lowering a ruler or caliper into one of them until it stops (using its depth gauge). If the measurement shows a level of 25-26 mm, it corresponds to the norm and no adjustment is required;

If the amount of fuel in the chamber is lower or higher than normal, we perform a visual inspection and a series of measurements on the floats, and if necessary, we correct their position.

To carry out adjustment work, place the removed carburetor cover on a flat horizontal surface with the floats facing up.

First, we look at the position of the elements from above. The outer side surfaces of the floats are parallel to the special imprints on the gasket. Deviations can cause the floats to touch adjacent elements and surfaces, causing the fuel level to be incorrect. If necessary, adjust the position of the floats by bending their mounting arms. The next step is to measure the gap between the floats and the gasket. A rod with a diameter of 2 mm is useful here - this is how much the specified gap should be.

If it does not correspond, we bend the tongue of the floats, with which they act on the locking needle. After this adjustment, we check the total height of the floats, which is normally 34 mm. If this is not the case, check the gap again, adjust it if necessary and measure the height again.

The last stage of setup is determining the working stroke of the floats. To do this, place a caliper near the float, mark the distance from its lower corner to the surface of the cover, then lift the float with your hand and mark where the lower corner is.

A working stroke of 15 mm is considered normal; if it differs, it is adjusted by bending the tongue.

Remove and wash the carburetor

Now we can talk directly about how to clean the carburetor on a VAZ 2109 by removing it and disassembling it.

1. Be sure to prepare an instruction manual, read it several times first, and understand all the intricacies of the work.
2. Unscrew the fasteners of the air filter cover, remove the filter and housing.
3. Remove the carburetor cover by unscrewing all screws.
4. Remove the float from the chamber, remove the gaskets, check their quality and replace with new ones, if necessary.

8. Unscrew the plugs and pay attention to the copper sealing washers. If they are deformed, be sure to replace them with new ones.
9. Unscrew and remove the main fuel jets from the housing, doing this as carefully as possible. Mark each jet and the location where it was installed so that you can reassemble it in the same order.
10. Remove the fuel filter, soak it in acetone and blow with compressed air, then put it back in place.
11. Fill the float chamber with fuel, and use a tire pump to blow out the emulsion channels.
