2–screw of adjustment of a gap of an air zaslonka;

3–drill;

4–air zaslonka of the carburetor

PERFORMANCE ORDER
1. In the carburetor with manual podsosy to disconnect a cable 5 (see fig. Fastening of draft of an air zaslonka on the carburetor 31P1C-7) from the lever 1. To turn the lever 1 so that the air zaslonka was closed. To uncover 31 (see fig. Carburetor 31P1C-7 details) together with a bimetallic spring.
2. In the carburetor with automatic podsosy to uncover 31 with a bimetallic spring. To close an air zaslonka.
3. To drown draft of 1 diaphragm of a pneumodrive of an air zaslonka against the stop.
4. To measure a gap between an air zaslonka and a mouth. It should be equal 1,6–2,0 mm. It is possible to measure a gap by means of a drill.
5. If the gap does not keep within the specified limits, to adjust it screw 2 rotation, previously having removed from the screw a protective cap.
6. To establish into place a cover 31 (see fig. Carburetor 31P1C-7 details) so that the label on a cover coincided with a label on the carburetor case.
7. At carburetors with manual podsosy to connect a cable 5 (see fig. Fastening of draft of an air zaslonka on the carburetor 31P1C-7).
