11.19г the Arrangement of the electromagnetic valve of adjustment of structure of a mix

11.19д At replacement of the electromagnetic valve remove the plug (1) from an underside of a socket of connection, having pressed on a uvula located near the plug, a screw-driver. For removal of the electromagnetic valve of ventilation поплавковой chambers (2) turn off three fixing screws

19. Disconnect a connection socket. Check up resistance of windings of solenoids and replace them if it is necessary (11.19а, 11.19б, 11.19в, 11.19г and 11.19д).

11.20 For check of the gauge position throttle заслонки disconnect a socket of connection and measure resistance between plugs 2 and 3

20. Check up resistance between plugs 2 and 3 gauges and check up, that resistance gradually changed at opening throttle заслонки (11.20).

11.21 Check up, that the cam of fast idling was free (the lever should not rest against a cam) 1. A cam of fast idling 2. The lever

21. Warm up the engine. Ослабьте a tension of a rope of an accelerator also check up, that the cam of fast idling was free (11.21). Muffle the engine.

11.22 Turn off adjusting screws SAS-1 and SAS-2 that throttle заслонка it has been completely closed, counting up number of turns

22. Including number of turns, turn off adjusting screws of speed of work of the engine (SAS-1 and SAS-2) (11.22) that throttle заслонка it has been completely closed.

11.23а If on your car such type of the gauge position throttle заслонки (1) is established, for its adjustment use the screw (2).

11.23б If on your car such type of the gauge position throttle заслонки is established, turn off fixing screws and adjust the gauge, having turned it 1. The position gauge щюссельной заслонки

23. Check up pressure of the gauge at the included ignition between plugs 2 and 3 and adjust it if it is necessary, rotating the adjusting screw or having turned the gauge (11.20, 11.23а and 11.23б).

24. Switch off ignition.

25. Twirl adjusting screws SAS-1 and SAS-2 on the same number of turns, that they have been turned off.

26. Adjust a tension of a rope of an accelerator. Start the engine and check up speed of idling.

27. Warm up the engine and switch off all electric equipment.
