Remove air filter.
After adjusting the clearance of the starting damper, it is necessary to check the play between the lever of the retaining damper and the rod.
To do this, with the help of a vacuum pump, create a low pressure in the vacuum regulator until the rod is fully retracted.
Backlash value -A- of retaining flap lever, see table.
Adjustment is made by bending the end of the rod.
Install the air filter.
Attention! If this adjustment does not help, then an additional damping valve ET-831790 is installed, if not built-in, in the vacuum channel, between the carburetor and the vacuum regulator. Moreover, the conical part of the valve should look towards the carburetor. For conversion, use a new vacuum hose.
