|
|
1–draft of a diaphragm of a pneumodrive of an air zaslonka;
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). |
|

| 6. To measure amount of fuel in a beaker and to divide on 10. Let's receive amount of fuel which submits the accelerating pump for one cycle. This value should make 0,85–1,1 cm3. |
| 7. If necessary to adjust productivity of the accelerating pump a nut 1 or the screw 2. |
| 8. To pay attention to that fuel from a spray was injected into a gap between a butterfly valve and a mouth. If it is necessary, it is possible to turn in a spray of the accelerating pump. |
|
Adjustment of frequency of rotation of idling
Adjustment make on the heated-up engine with the adjusted gaps in the mechanism of a drive of valves and correctly established moment of ignition in the following order:
| PERFORMANCE ORDER |
| 1. To disconnect everything consumers of energy. |
| 2. To disconnect from the air filter a hose of ventilation of a case and to muffle it. |
