Check conditions: an ambient temperature 20 With.

Check of position of a moved roller at adjustment of additional opening throttle заслонки the first chamber

1 – the adjusting screw,

2 – a moved roller,

3 – a screw-driver for adjustment of a moved roller,

4 – a measuring core in diameter 3 mm,

5 – a template 180 143 Т

PERFORMANCE ORDER
1. By means of a measuring core (or drills) diameter 3 mm to check up opening throttle заслонки the first chamber.
2. In case of need to establish necessary size by means of the screw (1).

THE CARBURETTOR IS ESTABLISHED

PERFORMANCE ORDER
1. To check up position of a moved roller. For this purpose follows:
      – To insert a template (5 180 143 Т, as on fig. Check of position of a moved roller at adjustment of additional opening throttle заслонки the first chamber;
      – To check up, whether there is a moved roller (2) between two cuts of a template (5);
      – In case of need by means of a screw-driver (3) to execute adjustment by the adjusting screw and a core (4) diameter of 3 mm.
2. To take a template.
3. To start the engine.
4. To place circular cut of a template on a moved roller and to turn a template (5) so that to join it with the top wall of the case of the starting arrangement (1 – the adjusting screw).
5. Speed of rotation of the engine should be in limits of 2350-2450 rpm if the carburettor is supplied by a plate on a starting arrangement cam, or 1700–1800 rpm if the carburettor has no such plate.
6. In case of need to execute adjustment by means of the adjusting screw.

Check and adjustment of opening air заслонки

Adjustment приоткрывания air заслонки on the removed carburettor

1 – a core,

2 – the adjusting screw,

3 – a counternut

This operation can be carried out both on removed, and on the carburettor established in the car.

THE CARBURETTOR IS REMOVED

Check conditions: an ambient temperature 20 With.

PERFORMANCE ORDER
1. Tweezers to undertake a core (1) (cм. Fig. Adjustment приоткрывания air заслонки on the removed carburettor) and to push it in a direction shown by an arrow, before contact to the screw (2).
2. By means of a drill in diameter of 6 mm to measure приоткрывание air заслонки.
3. In case of need to unscrew a counternut and by means of the screw (2) to establish necessary size.

THE CARBURETTOR IS ESTABLISHED

Adjustment приоткрывания air заслонки on the established carburettor
2 – the adjusting screw,

3 – a counternut,

4 – a template 180 143 Т,

5 – a measuring core in diameter of 6 mm

PERFORMANCE ORDER
