 PERFORMANCE ORDER

We adjust gates on the removed carburetor (see Replacement of the carburetor).

We turn the lever of the drive of butterfly valves before contact of the top short mustache of the lever of a butterfly valve of the first camera with the lever limiting opening of the gate of the second camera.

We measure a gap between the gate and a wall of the camera which has to be 6±0,25 mm in such situation.

If necessary we regulate a gap a podgibaniye of the top short mustache of the lever of an axis of a butterfly valve of the first camera.

Turning the lever, we open a butterfly valve of the first camera completely. The distance between a wall of the camera and the gate has to be 13±0,1 mm.

We regulate full opening of the gate of the first camera a podgibaniye of the lower short mustache of the lever of an axis of a butterfly valve.

The distance between the gate of the second camera and a wall has to be 17±0,1 mm. We regulate the size of the maximum opening of the gate change of length of a rod of a pneumatic actuator (see Repair of the carburetor).
