| 1. To uncover the starting arrangement (fig. of the Detail of the carburettor 1В3 see). |
| 2. Completely to open throttle заслонку. |
| 3. To connect the vacuum gauge and the vacuum pump to a pneumodrive air заслонки. To create in a pneumodrive depression 100 мбар. If the pneumodrive is tight, depression should not decrease more than on 5 мбар for a minute and decrease less than to 40 мбар. |
| 4. To finish depression to 200–300 мбар. |
| 5. To measure with the help probeов a starting backlash And between air заслонкой and a wall of a mouth of the first step air заслонки. For cars with five-step mechanical transmission it should be (2,3±0,15) mm, and for cars with automatic transmission (2,1±0,15) mm. If necessary to adjust a backlash the screw of adjustment of a course of a diaphragm of the pneumodrive, located in an end face of a cover of a pneumodrive. |
| 6. To close заглушкой an atmospheric aperture of a pneumodrive air заслонки. To create in a pneumodrive depression 200 мбар which should not vary during 1 mines if the pneumodrive is tight. |
| 7. To measure probeом a starting backlash And the second step air заслонки which should be (3,0±0,15) mm. |
| 8. If it is necessary, to adjust a backlash the screw in an end face of a rod of a pneumodrive air заслонки. |
| 9. A coupling guard. |
| 10. The bottom bolts of fastening картера couplings to the block of cylinders. |
