1. Remove the carburetor.

2. Remove springs of a butterfly valve.

3. Remove a hose of cooling liquid and a spring of a butterfly valve.

4. Remove the pneumoshock-absorber – the drawing at the left (on the car from the manual transmission) or the electropneumatic valve (on the car from the automatic transmission), having unhooked a rod.

5. On the car from the automatic transmission unscrew screws, remove the drive of the proofreader of idling and take aside (the proofreader tension from the battery is forbidden to check).

6. Remove a socket arm.

7. Disconnect a vacuum hose of the air gate.

8. Unscrew 5 screws and uncover the float-operated camera, slightly having hooked it.

9. Remove a float, get the needle valve and turn out a saddle.

10. The tiny screw-driver disconnect conclusions of the electromagnetic feedback-valve (FBSV valve).

11. Remove a cover, unscrew the screw (1) and remove the FBSV valve (2 – conclusions).

12. Remove the holder and get the electromagnetic gate-type valve (SCSV valve), without disconnecting wires.

13. The tiny screw-driver disconnect plugs of wires from the SCSV valve and remove it.

14. Remove heads of rivets and uncover a breaker of the air gate. Unscrew the small screw in the lower part of a cover.

15. Remove laying, a bimetallic element and a plate.

16. Carefully remove the remains of rivets.

17. Disconnect a conclusion of a bimetallic element from the socket.

18. Remove the ventilating valve, having paid attention to an arrangement of small springs of the valve.

19. Uncover the drive of the air gate (shooters specified screws of fastening of the air gate).

20. Get a counterbalance and the ball valve of the locking valve.

21. Disconnect draft of the accelerating pump from the lever of a butterfly valve.

22. Carefully turn out the screw from the case of a butterfly valve. Turn out the main jet.

23. Unscrew screws and get details of the accelerating pump from the case.

24. Unscrew 3 screws on a cover of the economizer and remove a cover, a spring and a diaphragm.

25. Disconnect a vacuum hose of the camera of depression, disconnect a rod, turn off bolts and remove the camera.

26. Remove the sensor of turn of a butterfly valve (it is specified by an arrow).

27. Wash out channels of the carburetor solvent and blow compressed air.

28. Check a condition of diaphragms, a float and the needle valve, freedom of movement of rods, drafts and levers. Check operation of solenoidal valves and resistance of their windings (the FBSV valve – 48–60 Ohms, the SCSV valve – 54–66 Ohms, a bimetallic element – 6 Ohms at 20 °C).

29. Check the pneumoshock-absorber, having pulled for a rod, – at the same time resistance has to be felt, at an otpuskaniye the rod quickly comes back.

30. Press a rod of the camera of depression and release, having closed a finger an opening for an air suction, – the rod has to remain motionless.

1. Air gate

2. Gap

3. The lever for adjustment

1. Mount the sensor of turn of the gate, the camera of depression, collect and install the economizer, the accelerating pump. Install the locking valve, a cover of a breaker of the drive of the air gate, the ventilating valve. Wrap the main jets.

2. Collect the socket of a bimetallic element. Establish an element upside-down, having replaced laying and having combined tags. Fix a cover by rivets, it is not recommended to use screws.

3. Collect FBSV-sockets and SCSV valves. Install valves and collect the case of the gate and the case of the diffuser, having replaced a sealant and having screwed the screw.

4. Establish all details on a cover of the float-operated camera. Adjust the provision of a float.

5. Establish a cover of the float-operated camera, fix by 5 screws. Establish a socket arm, the pneumoshock-absorber (or a pneumatic valve), all springs, levers and drafts. Check smoothness of movement of drafts.

6. Check a gap between a butterfly valve and a wall of the diffuser, having laid a drill and having transferred an idling cam to extreme top situation. The gap has to be 0,63 mm on the engine of 2,0 l (from the manual transmission), 0,71 mm on engines of 2,0 l (from the automatic transmission), 0,71 mm on engines of 2,6 l (from the manual transmission), 0,80 mm on engines of 2,6 l (from the automatic transmission).

7. Check a gap between the air gate and a wall of the camera at completely open butterfly valve. For this purpose a finger close the air gate and the lever open a butterfly valve. The gap has to be 2 mm. If necessary adjust a podgibaniye a rychazhka.

Prevention This gap after dismantling assembly should not change and as a rule is only checked. The wrong adjustment of a gap very strongly worsens road performance of the car at not heated-up engine.

8. Replace laying and install the carburetor (see subsection 8.1.2.1).
