Removal
PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the storage battery.
2. Merge cooling liquid to level below an inlet collector.
3. Uncover the carburetor.
4. Disconnect an accelerator cable from the butterfly valve lever.
5. Disconnect from the carburetor vacuum hoses.
6. Disconnect the socket from the electromagnetic valve of compulsory idling.
7. Place capacity under connections of fuel hoses for collecting the flowed-out fuel and disconnect hoses of supply of fuel from carburetor branch pipes.
8. Turn out bolts and remove the carburetor from the engine.

Dismantling
Prevention

Do not remove an air zaslonka and butterfly valves.

PERFORMANCE ORDER
1. On the carburetor with an automatic air zaslonka remove a hose of system of cooling from a branch pipe of the case of the carburetor.
2. Remove draft of the starting arrangement from the free lever.
3. Remove an arm with the socket.
4. Remove the starting arrangement.
5. Remove a core of the accelerating pump from the butterfly valve lever.
6. Uncover the poplavkovy chamber, turn out the screw "B" and remove the carburetor case.
7. Turn out screws "A" and uncover the poplavkovy chamber the main case.
8. For removal of a cover of the poplavkovy chamber insert an edge of a flat screw-driver between a cover and the main case and, operating with a screw-driver as the lever, slowly separate a cover.
Prevention

At removal of a cover do not apply excessive force.
9. Remove a hairpin and then remove a float and the needle valve.
Prevention

Do not drop a float.
Be careful not to damage the needle valve.
10. A flat screw-driver as the lever, take a nest of the needle valve.
Prevention

At extraction of a nest of the needle valve do not damage the poplavkovy chamber.
11. Remove the holder and the electromagnetic valve of compulsory idling.
12. A screw-driver with a thin edge wring out clamps and get two contacts from the socket of the electromagnetic valve of compulsory idling.
13. Remove an arm of support of a cable of an accelerator.
14. Remove jets of idling and the main air jet.
Prevention

For removal of jets use a screw-driver with a thin edge and work carefully not to damage jets.
15. Remove the accelerating pump and check a ball and грузик.
Prevention

To remove the accelerating pump, do not overturn the case with mixing chambers. Check a ball and грузик through openings in laying.
16. Separate the poplavkovy chamber from the carburetor case.
17. Remove the main jets.
Prevention

For removal of jets use a screw-driver with a thin edge and work carefully not to damage jets.
18. Turn out three screws of fastening of a cover of the valve of enrichment of a fuel mix to the case of the poplavkovy chamber. Uncover, a spring and a diaphragm.
19. A screw-driver weaken a tube of enrichment of a fuel mix and remove a spring and a ball.
Prevention

The valve of enrichment of a fuel mix consists of many small details. Do not lose them.
20. Turn out four screws of fastening of the accelerating pump to a cover of the poplavkovy chamber. Uncover the pump, a diaphragm, a spring and laying.
Prevention

Before a vvorachivaniye of screws of fastening of the accelerating pump put on their carving the blocking structure interfering their otvorachivaniye.
21. Remove an E-shaped clip and washers from an axis of a butterfly valve of the secondary chamber and remove a diaphragm spring.
22. Turn out two screws of fastening of an arm of a diaphragm to the case of the carburetor and remove a butterfly valve diaphragm.
23. Remove the auxiliary accelerating pump.
24. Drill an opening in diameter of 2 mm in the central opening for the screw of adjustment of a fuel mix (MAS), then рассверлите an opening a drill in diameter of 3 mm. Insert into the drilled opening a drift and beat out a stopper.

Assembly

Assembly is carried out in sequence, return dismantling, taking into account the following.
PERFORMANCE ORDER
1. Before assembly clear all details.
2. Check that air and fuel channels are not littered.
3. At replacement of jets the same sizes as jets steal up at plant on their productivity should have an old and new jet.
4. Do not use repeatedly sealing rings and laying.

Check

Check a condition and replace or if it is necessary, repair the following details.

PERFORMANCE ORDER
1. Check that air and fuel jets are not littered. If they are littered, wash out them in solvent and blow the compressed air. For cleaning do not use a metal wire.
2. Check diaphragms on absence of damages and cracks.
3. Be convinced that the needle valve moves easily. If the valve moves hardly or gets jammed, repair or replace it.
4. Check on lack of a contamination the entrance fuel filter located over the needle valve.
5. Check a float course.
6. Check action of a butterfly valve, an air zaslonka and drafts. If they move hardly, wash out them and grease their axes with pure engine oil.
7. Check a cover of the poplavkovy chamber and the carburetor case on absence of damages and cracks.

Check of the electromagnetic valve of compulsory idling (SCSV)

PERFORMANCE ORDER
1. Additional wires submit tension of the storage battery to contacts of the socket of the electromagnetic valve of compulsory idling.
2. Be convinced that the valve works with accurate click.
3. An ohmmeter check that there is no conductivity between contacts of the socket and the case of the electromagnetic valve of compulsory idling.
4. By an ohmmeter measure resistance between contacts of the socket of the electromagnetic valve of compulsory idling.

Resistance: 48-60 kiloohms at 20°C

Gap check priotkrytiya of a butterfly valve of the primary chamber

PERFORMANCE ORDER
1. By a shaft of a drill measure a gap between a butterfly valve of the primary chamber and the case.

Gap: 0,93 mm
2. If the gap does not correspond demanded, adjust it, rotating the adjusting screw. For increase in a gap rotate the screw clockwise, for gap reduction - counter-clockwise.

Installation
PERFORMANCE ORDER
1. Check a condition and, if necessary, clear interfaced surfaces of the carburetor and an inlet collector.
2. Establish new laying of the carburetor on an inlet collector.
3. Carefully establish the carburetor on an inlet collector.
4. Gradually, in turn, screw bolts of fastening of the carburetor in order that laying was compressed evenly. Bolts are necessary for tightening very reliably to exclude подсос air between the carburetor and an inlet collector.
5. Connect an accelerator cable, vacuum hoses and hoses of supply of fuel.
6. Check reliability of connection of vacuum hoses.
7. Check that the air zaslonka opens completely and closed.
8. Check that by pressing of a pedal of an accelerator the butterfly valve completely opens.

Prevention

Before the first start-up do not fill in fuel in an air mouth of the carburetor for acceleration of start of the engine after service of fuel system. For a zakachivaniye of fuel turn a cranked shaft of the engine a starter.
11. Check frequency of idling and, if necessary, adjust it.
