For more than 100 years, carburettors have dominated theall gasoline cars. With the introduction of injection injection systems, these devices have practically ceased to be improved. But carburetor cars are still coming off the conveyors of domestic automobile plants. And although the volume of their production has decreased significantly, they will continue to be exploited for a very long time. Sometimes they fail, and then repair of Solex-carburetor is necessary.
If the car engine does not start orworks, but quickly stalls, this can be caused by the lack of fuel in the float chamber. Also, the composition of the fuel mixture may be disturbed. If the engine is idling very unstable, there may be several problems.
High idling speed
If low or very highidling speed, this may be caused by malfunctions in the adjustment or an incorrect level of fuel in the chamber. In addition, air or fuel jets could be clogged. It is also possible in the case of partial opening of the air damper. It is necessary to carry out adjustment, and in some cases also repair of Solex-carburetor.
Poor start-up of the motor and increased consumption
If the cold engine starts badly, then thiscan be a sign of improper adjustment of the trigger. If the air damper is partially closed, this can lead to excessive depletion of the combustible mixture. This phenomenon is caused by the absence of flares in the combustion chambers. Incorrect opening of the damper after the engine is started leads to enrichment of the mixture, as a result of which the engine "chokes".
Carburetor VAZ "Solex" may require repairor maintenance in the event that a warm engine is started badly. This can be caused by the fact that the combustion chamber receives too rich a mixture, which is caused by a high level of combustible fuel in the float chamber. The reason for this is a malfunctioning or lack of tightness of the fuel valve.
If the car began to consume more fuel,then it can also be caused by a variety of reasons. And often the carburetor requires maintenance. There are many reasons why drivers are forced to constantly adjust this mechanism.

The correct location of the floats - exactlycenters of prints. The lateral surfaces of these should be strictly parallel to the walls of the chamber. In order to change the position of the parts, it is necessary to bend the holders in the desired direction. If they suddenly have damage on the gasket, you can get a print on the new one. For this, the bogie plane is covered with waste oil, and the lid is pressed against the body of the carburettor.
The lid should take a horizontal position,floats are sent upwards. The support surface of the tongue of the bracket is perpendicular to the axis of the needle valve. If there are violations, then the problem can easily be eliminated with the help of pliers. If the support surface is deformed, the floats are removed and leveled. If the damage is serious, a replacement is required.
To adjust the fuel level, the coverturn so that the floats are looking up, and set it on a horizontal surface. The damper ball should be as much as possible drowned in the valve needle. It is important to monitor the clearances - they should be the same and approximately equal to 0.25 mm. In case of deviation with the help of bending the holders, it is possible to adjust the gap.
How to check the needle valve
To do this, remove the cover of the device. As carefully as possible, not to damage the floats, the lid is placed on a horizontal surface. Next, put a piece of hose on the fitting. After that, the most tightly closing the fuel return element, create a vacuum in the hose with a pear.
