5.6. Carburettor adjustment
THE GENERAL DATA

Adjustment of the raised turns of idling

The raised turns of idling are established at opening throttle заслонки on a certain corner through mechanical draught. The corner of opening throttle заслонки the primary chamber at a finding of a cam of a regulator of fast idling in position 1 should be 16 With, secondary – 18 With.

Adjustment throttle заслонки the primary chamber

1 – air заслонка

2 – draught air заслонки

3 – throttle заслонка the primary chamber

4 – a measured backlash

5 – throttle заслонка the secondary chamber

6 – a cam of the raised turns of idling

Throttle заслонка the primary chamber opens the screw of adjustment of the raised turns of idling at full closing air заслонки. The corner of opening throttle заслонки the primary chamber is checked as follows.

PERFORMANCE ORDER
1. Close air заслонку to the full and check up a backlash between edge throttle заслонки in an average part and a chamber wall. This backlash should be within 1,3–1,5 mm.
2. Rotating the screw, adjust the specified backlash.

The prevention

Before backlash check completely screw the screw of restriction of a course throttle заслонки.


Adjustment of the lever of switching on a hill-climbing gear (the kick-down-mode lever)

1 – throttle заслонка the primary chamber it (is completely closed)

2 – the screw

3 – a counternut

4 – the kick-down-lever

5 – a plate of the lever of return

6 – a roller

PERFORMANCE ORDER
1. Completely close throttle заслонку the primary chamber for what turn away the adjusting screw.
2. Release a counternut of the lever of switching in a kick-down-mode and rotate the screw against the stop in a plate of the lever of return.
3. Tighten a counternut.

Adjustment air заслонки on cars Amigo/MU/Jazz 1988-1995


PERFORMANCE ORDER
1. Expose the adjusting screw of the raised turns of idling opposite to 2nd position of a cam.
2. Check up a backlash between edge air заслонки and a chamber wall.
3. The backlash should be within 0,8–1,3 mm. In протинм a case it is necessary to turn in the termination of the lever before reception of the necessary backlash.

Adjustment of a drive of restriction of turns at full opening throttle заслонки on cars Amigo/MU/Jazz 1988-1995


PERFORMANCE ORDER
1. Completely open throttle заслонку the primary chamber.
2. Check up a backlash between edge air заслонки and a chamber wall.
3. The backlash should be within 2,5–3,3 mm. Otherwise turn in the termination of the lever before reception of the necessary backlash.

Adjustment throttle заслонок primary and secondary chambers on cars Amigo/MU/Jazz 1988-1995

PERFORMANCE ORDER
1. Slowly open throttle заслонку the primary chamber against the stop the kick-down-lever terminations in a plate of the lever of return.
2. Check up a backlash between edge air заслонки and a chamber wall.
3. The backlash should be within 7,0–8,5 mm. Otherwise turn in the termination of the kick-down-lever before reception of the necessary backlash.
