As a rule, carburetors of stamps - Solex, Ozone or Weber were included in the package of old VAZ models. Moreover, for many years of operation, their popularity has not decreased, but on the contrary - increased. But under the influence of time, carburetors are able to fail and require settings, cleaning, as well as repair. Since these operations in specialized workshops are not suiced, the independent repair of VAZ carburetors has become one of the most relevant topics for discussion.

When cleaning the bottom of the float chamber, it is impossible to use a rag, as it can lead to the appearance of fibers on the bottom, resulting in a carburetor jet. To clean, it is desirable to use compressed air or rubber pear.

When checking the shut-off needle for tightness, a pear is also used, as the pressure that appears due to the compression of this item with hands, roughly corresponds to the pressure of the fuel pump. When you install the carburetor cover, check whether the float is installed. In the process of installation, a significant pressure is felt. In this moment, the carburetor needs to be listening, since the air leakage is unacceptable. Even with the minimum leak itself, you need to change the needle and valve body.

Idling adjustment, step-by-step instruction

Option setting must be performed after preheating vehicle. With the help of the quality screw, you should adjust the maximum revolution rate, while you do not need to turn the screw the screw.
