1 – carburetor cover;
2 – saddle of the needle valve;
3 – emphasis;
4 – needle valve;
5 – ball of the needle valve;
6 – ottyazhny fork of the needle valve;
7 – float lever uvula;
8 – float;
9 – laying of a cover of the carburetor; |
Adjustment of level of fuel in the float-operated camera is carried out through each 30 thousand km, and also at the increased fuel consumption, replacement of the needle valve or a float.
| PERFORMANCE ORDER |
| 1. To uncover 1 carburetor and to be convinced that the float 8 has no dents and holes freely shakes on an axis, and its weight together with the mass of the lever is equal (12±1) g. |
| 2. To check saddle inhaling density 2 needle valves in a cover 1 and lack of jammings of a ball of the 5th needle valve 4. |
| 3. To establish a cover 1 vertically by the fuel supply union up. At the same time the needle valve 4 has to be closed, and the uvula of the 7th lever of a float to touch a ball of the 5th needle valve, without squeezing a ball spring. |
| 4. To check in this situation a gap And between a middle part of a float and the surface of the laying 9 which is densely pressed to a cover flange. The gap has to be equal (6,5±0,25) mm. If necessary it is careful to turn in a uvula 7 for receiving the required gap. The uvula 7 has to be perpendicular axes of the needle valve, and its contact surface from a ball should not have damages which can be the cause of lag of the valve. |
| 5. To check the course of a float which has to be (8±0,25) mm, if necessary turn in an emphasis 3. |
| 6. To check whether the ottyazhny fork of the 6th needle valve interferes with its free movement. |
| 7. To establish a cover of 1 carburetor into place, having convinced that the float can freely move, without touching walls of the float-operated camera. |

1 – float;
2 – float lever uvula;
3 – valve;
4 – laying of a cover of the carburetor;
5 – carburetor cover |
Adjustment of level of fuel in the float-operated camera is carried out through each 30 thousand km.
| PERFORMANCE ORDER |
| 1. To establish a cover of the 5th carburetor horizontally, floats up. |
| 2. In this situation to check a gap between each float and laying 4, skintight to a cover. The gap has to be identical under each float and is equal (1±0,25) mm. If necessary 2 levers of a float for receiving the required gap are careful to turn in a uvula. The basic surface of a uvula has to be perpendicular axes of the needle valve 3 and should not have dents and забоин. For observance of the above-stated conditions and an exception of a possibility of a zadevaniye of floats for walls of the float-operated camera the careful podgibaniye of yokes of floats in the required plane is allowed. |
|
Prevention
It is necessary to check installation of a float always when replacing a float or the needle valve; in the latter case it is necessary to replace also sealing laying of the valve.
