4–carburetor case;
5–electromagnetic valve;
6–persistent screw;
7–cover of the accelerating pump;
8–pump diaphragm;
9–spring;
10-valve saddle;
11-valve of the accelerating pump;
12-ekonomayzer of moshchnostny modes;
13-spray of the accelerating pump;
14-laying of a cover of the carburetor;
15-float;
16-main fuel jet of the first chamber;
17-needle valve;
18-filter;
19-main fuel jet of the second chamber;
20-float axis;
21-idling jet;
22-tube of an ekonomayzer;
23-carburetor cover;
24-pneumodrive of an air zaslonka;
25-automatic starting arrangement;
26-cover of the starting arrangement;
27-pneumodrive of a butterfly valve of the second chamber

If when dismantling the carburetor the ekonomayzer of 12 moshchnostny modes acts in film, it is necessary to replace it.

Check of the electromagnetic valve

To check serviceability of the electromagnetic valve 5, it is necessary to disconnect from it a wire. To connect to the valve a wire which second end is connected to the positive plug of the storage battery. Thus should the crash will be distributed. If it does not occur, the valve means is faulty and it is necessary to replace it.

Adjustment of a gap of an air zaslonka

PERFORMANCE ORDER
1. To uncover 26 starting arrangements.
2. To open a butterfly valve of the first chamber and to turn a cam 1 (see fig. Adjustment of frequency of rotation of start-up of the engine) an air zaslonka so that the screw of 2 adjustments of frequency of rotation of start-up rested against the highest ledge of a cam.
3. Through an opening 1 screw-driver to move draft of a pneumodrive of an air zaslonka against the stop. To measure a gap between an air zaslonka and a mouth, it should be 2,0±0,1 mm. It is possible to measure a gap by a drill in the 2nd diameter of 2 mm. If the gap differs from specified, it is necessary to insert 1 screw-driver into an opening and, turning the adjusting screw, to adjust a gap.

Adjustment of the accelerating pump

PERFORMANCE ORDER
1. To remove the carburetor.
2. To uncover the carburetor, to fill with fuel the poplavkovy chamber and to establish a carburetor cover.
3. To turn a cam 1 (see fig. Adjustment of frequency of rotation of start-up of the engine) so that it did not concern the screw 2.
4. To put under the carburetor a measured beaker with a funnel.
5. Holding a cam 1 in this situation, smoothly to turn a butterfly valve of the first chamber from an emphasis against the stop 10 times, spending for each course 1 with and maintaining then a pause in 3 with, putting these in action the accelerating pump.
6. To measure amount of fuel in a beaker and to divide on 10. The amount of fuel which submits the accelerating pump for one cycle will turn out. This value should make 1,0±0,15 cm3.
7. If the received size differs from specified, it is necessary to adjust productivity of the accelerating pump. For this purpose to weaken an inhaling of the screw 1 and to turn a cam 2. At cam turn aside "And" productivity of the pump increases, aside "In" – decreases. To tighten the screw 1 and законтрить paint.

Check of the automatic starting arrangement

For check of the automatic starting arrangement it is necessary to disconnect a device wire from a connecting block. To connect to a device wire a lamp. The second wire from a lamp to connect to the positive plug of the storage battery. The lamp should burn. If the lamp does not burn, the starting arrangement is faulty and it is necessary to replace it. It is necessary to pay attention, that labels on a cover and the case of the starting arrangement coincided.

Adjustment of a priotkryvaniye of a butterfly valve of the second chamber

1–butterfly valve lever;

2–persistent screw;

3–emphasis;

the arrow showed a wooden core

The provision of a butterfly valve is adjusted at manufacturer, and in use adjustment is not required. If adjustment was broken, it can be restored as follows:

PERFORMANCE ORDER
1. Completely to open a butterfly valve of the first chamber and to fix in this situation by a wooden core.
2. To turn the lever 1 so that the butterfly valve of the second chamber was closed. To block the lever 1 elastic band, as is shown in drawing
3. To turn out the persistent screw 2 that it did not concern an emphasis 3.
4. To wrap the screw 2 to a contact with an emphasis 3 and then to wrap it on a turn quarter (90 °). Законтрить screw 2 paint.
5. To remove an elastic band and to take out a wooden core. Both zaslonka should be closed.
6. To measure internal "And" and external "In" gaps. The gap "And" should make 0,4±0,1 mm, a gap "In" 1,0±0,1 mm.
7. If gaps differ from specified, to adjust them, turning in the ends of a fork of the lever 1.

Check of a pneumodrive of an air zaslonka

PERFORMANCE ORDER
1. To remove the air filter.
2. To start the engine and to leave to idle.
3. A hand smoothly to close an air zaslonka till the moment when appreciable resistance will be felt. During this moment the gap between an air zaslonka and a mouth should be about 4 mm.
4. If resistance it is not felt, to check vacuum hoses – whether there are no in them cracks.
5. If hoses whole to connect to a pneumodrive the vacuum gage and the vacuum pump. To create in a pneumodrive depression of 300 Mbar. If the pneumodrive is serviceable, depression should not fall within 2 minutes. If depression falls, the pneumodrive means is not tight and it is necessary to replace it.

Check of a pneumodrive of a butterfly valve of the second chamber

PERFORMANCE ORDER
1. To connect to a pneumodrive the vacuum gage and the vacuum pump.
2. To create in a pneumodrive depression of 50 Mbar. If depression does not fall during 2 mines, the pneumodrive is tight. Otherwise a pneumodrive to replace.

Adjustment of frequency of rotation of start-up of the engine
1–cam of an air zaslonka;

2–screw of adjustment of frequency of rotation of start-up of the engine

2. To connect to the engine a control tachometer.
3. To start the engine and to slightly open a butterfly valve of the first chamber before obtaining frequency of rotation of the crankshaft about 2500 mines-1.
4. To turn a cam 1 against the stop. Then to turn a butterfly valve so that the adjusting screw 2 rested on the ledge second for height.
5. To check on a control tachometer frequency of rotation of the engine, it should make 2000±100 mines-1. If frequency of rotation differs from specified, to adjust it the screw 2.

Adjustment of frequency of rotation of idling

Adjusting screws

1–screw of adjustment of quantity of a mix;
2–screw of adjustment of quality (structure) of a mix;

2. To disconnect from the air filter a hose of ventilation of a case and to muffle it.
3. To connect a control tachometer and a gas analyzer.
4. To turn a cam 1 (see fig. Adjustment of frequency of rotation of start-up of the engine) so that it did not concern the screw 2.
