| 1. To uncover the starting arrangement (see rice. Carburetor 2E2 details). |
| 2. To delay down a control lever the air gate and to fix in this situation. |
| 3. To connect the vacuum gage and the vacuum pump to a pneumatic actuator of the air gate. |
| 4. To create depression of 100 Mbar in a pneumatic actuator. If the pneumatic actuator is tight, depression should not fall more than on 5 Mbar a minute and decrease less than to 40 Mbar. |
| 5. To bring depression in a pneumatic actuator to 200–300 Mbar. |
| 6. To measure by means of probes a starting gap And (see rice. Carburetor 1B3 details) the first step of the air gate, it has to be (1,8±0,15) mm. If necessary to adjust a gap turn of the screw of adjustment of the course of a diaphragm which is located in a pneumatic actuator cover end face (see rice. Carburetor 2E2 details). |
| 7. To close a cap an atmospheric opening of a pneumatic actuator and to create in it depression of 200 Mbar which should not change within 1 min. if the drive is tight. |
| 8. To measure by the probe a starting gap And the second step of the air gate which (4,0±0,15) mm for the car with mechanical transmission and (3,9±0,15) mm for cars with automatic transmission have to be. |
| 9. If it is necessary, to adjust a gap the screw in an end face of a rod of a pneumatic actuator of the air gate. |
