In this article you will learn how is the carb adjustment “Solex 21083”. Independently perform this work relatively quickly. Unless, of course, not going to make any improvement (tuning) of the fuel injection system. It is worth noting that the carb – based power system is that it is the proper mixture formation for subsequent supply to the cylinders of the engine. And depending how well this device works depends on technical condition of the car. What concerns 21083 carburetor, it is a very reliable device, which can serve as without the settings long enough. Provided that the mode of operation is close to perfect.

Basic information

adjusting the carburetor Solex 21083

Carburetors “Solex” may be different, but in fact the VAZ-21083 established the basic design. It uses the minimum cross-section diffusers. It is worth noting that these carbs can be used only on vehicles, the volume of which not more than one and a half liters. Also it should be noted that this carburetor can be installed on the engine VAZ-2108 and such, but motors car “classic” series. They easily installed the carburetor “Solex 21083”. The scheme of this device is given in the article.

“Solex” as a subject for tuning

There is a very large Playground for rampant imagination, if you are going to spend tuning the injection system. You can counterbore the carb under a different diameter diffusers. With regard to the installation of the engines, the volume of which is three pints, then this is not recommended, since the high rotational speed of the crankshaft it is not able to work normally. And it will not help adjusting the carburetor "Solex 21083”, as it is not designed for motors with a large volume. It should also be noted that the carburetor eights makes a lean mixture.

Start adjustments

jets carburetor Solex 21083

Note that setting the carburetor “Solex 21083” begins with adjustment of minimum level in the float chamber. To properly carry out this procedure, you will need a special template. The position of the floats should be at a certain distance from the lid. You can then proceed to setting the idle speed. For this, you need to fully tighten the screw that adjusts the quality of the mixture. Then twist it five or six turns. After remove the screw that regulates the amount of the mixture, achieving the disappearance of the vacuum in the tube connecting the carb and the distributor. Next you need to sharply press the accelerator pedal to check whether the engine operates in transient modes, if so configured carburetor “Solex 21083”.

Set idle

Then note the tachometer. It should be about 800 rpm. If you have screw number to reduce the speed, twisting it. In the same case, if the rotation speed is below 800 rpm, to spin a high-quality screw mixture until then, until the engine normalizes their work. But the carb adjustment “Solex 21083” is not finished. In your task is the maximum impoverishment of the working fuel-air mixture. Please note that when screwing in the mixture screw becomes poor. Consequently, this is reflected in the level of CO2. Now you need to screw in number to achieve a normal speed. If we are talking about the warm cycle of the year, it should be set in the range of 800-900 rpm. In winter it is better to increase this value by approximately 100 rpm.

Selecting and installing nozzles

That's all carb setting “Solex 21083” is completed, we can now talk about another important point. For carburetor Lada-2108 need to pick up the jets, and be sure to consider the volume of the engine. The higher the rate, the less must be the nozzles. And the reason is that with larger volume increase of the air passing through the diffuser. Consequently, this affects the consumption of gasoline. To pick up on the carburettor “Solex” the right nozzles, you must follow a particular algorithm.

The First thing recommended to pick up the petrol nozzle. Only when they need to make a selection air. And primarily is the selection of the device for the primary chamber, after – secondary.

If you decide to install a new carburetor “Solex 21083" (its price - about 3000 rubles), be sure to perform adjustment with the use of special equipment.

Enhancements carb

Very often made tuning carburetors that ends to improve the efficiency of this mechanism. In particular, motorists often remove the electric drive to work at idle. Of course,in this case, the increase in consumption of gasoline by about 5 percent. But the total capacity of the engine increases. Can also help the installation of a needle valve of a different design and the choice of the level of gasoline in the float chamber. With this you can reduce the likelihood that the air-fuel mixture will be too poor in the mode of increased capacity. As well as using a needle valve made of rubber, to keep the gasoline level as stable as possible. You can still replace the nozzles of the carburetor “Solex 21083”, this will allow to increase power. However, consumption of gasoline will also rise.

More serious revision

The carburetors of automobiles very often produce “cutting” of the throttle. This requires the throttle valve to make holes, whose diameter is somewhat less than was originally. It also significantly decreases the level of CO2 in the exhaust gases. But, on the other hand, during operation at idle speed CO2 level remains the same, it works in the default mode the carburetor “Solex” 21083. Device it only becomes such that the mixture is distributed more evenly. And you get the savings of gasoline, however small. Max can reduce gasoline consumption by two percent. After polishing diffusers really to reduce losses on aerodynamics. Of course, in order to achieve maximum effect, they must be polished to almost a mirror. This enhancement, which will improve the design of the carburetor “Solex”. On the other hand, this element of the power system is very stable, even without tuning it works perfectly. However, sometimes requires adjusting the carburetor "Solex 21083”.

Conclusion

It should also be noted that excessive wear of the engine – is to increase the probability that the vent tube begins to penetrate the coking chamber of the carburettor. If the engine on your car requires repairs, do it. If there is no way to pull it off air filter housing breather pipe. Point it under the crankcase of the engine to gases left in fuel system. But still not worth it to delay the overhaul. It is necessary to carry out repair and Troubleshooting of all auxiliary equipment.
