Check the solenoid valve
In order to check the serviceability of the solenoid valve 5, it is necessary to disconnect the wire from it. Connect the wire to the valve, the second end of which is connected to the positive terminal of the battery. This should hear a crack. If it does not, then the valve is defective and must be replaced.
Adjusting the choke gap
| PERFORMANCE ORDER | | 1. Remove the cover 26 of the starting device. | | 2. Open the throttle to the first chamber and turn the cam 1 (see. Fig. Speed control engine start) the air damper so that the screw 2 speed control start-up ended at the highest cam lobe. |  | 3. Through Hole 1 screwdriver move the choke actuator rod until it stops. To measure the gap between the choke and the neck, it should be 2,0 ?� 0,1 mm. The gap can be measured drill diameter 2 mm 2. If the gap is different from the need to insert a screwdriver into the hole 1 and turning the adjusting screw to adjust the gap. |

Adjusting the accelerator pump
| PERFORMANCE ORDER | | 1. Remove the carburetor. | | 2. Remove the cover of the carburetor float chamber filled with fuel and set the carburettor cover. | | 3. Turn cam 1 (see. Fig. Speed control engine start) so that it does not touch the screw 2. | | 4. Put a carburetor measuring beaker with a funnel. | | 5. Holding the cam 1 in this position, the throttle smoothly rotate the first chamber from stop to stop 10 times, spending 1 with each stroke and then soaking pause in 3, resulting in the effect these accelerating pump. | | 6. Measure the amount of fuel in a beaker and divide by 10. obtain an amount of fuel that the pump delivers the accelerator per cycle. This value should be 1,0 ?� 0,15 cm 3. |  | 7. If the obtained value is different from the above, it is necessary to adjust the performance of the accelerator pump. To do this, loosen the screw 1 and turn the cam 2. When you turn the cam in the direction of "A" pump output increases toward the "B" - is reduced. Tighten the screw 1 and lock paint. |

Check the automatic starting arrangement
To check the automatic starting device, disconnect the device from the wire connecting pads. Connect the device to the wire lamp. The second wire of the lamp connected to the positive terminal of the battery. The lamp should be on. If the lamp is not lit, the starter is faulty and must be replaced. It should be noted that the marks on the lid and the housing of the starting device match.
Adjusting the throttle priotkryvaniya second chamber | 1 - throttle lever;
2 - stop screw;
3 - an emphasis;
arrow shows a wooden rod |
Throttle position is adjusted at the factory, and in the process does not require manual adjustment. If the adjustment has been broken, it can be restored as follows:
| PERFORMANCE ORDER | | 1. Fully opening the throttle valve of the first chamber and fixed in this position, a wooden core. | | 2. Turn the lever 1 so that the throttle valve of the second chamber is closed. Lock lever 1 rubber band, as shown in Figure | | 3. Remove stop screw 2 so that it does not touch the stop 3. | | 4. Tighten the screw 2 until it touches the stop 3 and then wrap it for another quarter of a turn (90 ?�). Lock the screw 2 paint. | | 5. Remove the rubber band and remove the wooden rod. Both valves must be closed. |  | 6. Measure the internal "A" and the external "B" gaps. The gap "A" should be 0.4 ?� 0.1 mm, the gap "B" 1,0 ?� 0.1 mm. | | 7. If the gaps are different from the above, adjust it, bending the ends of the fork arm 1. |
|
Check the air damper actuator
| PERFORMANCE ORDER | | 1. Remove the air filter. | | 2. Start the engine and run at idle. | | 3. Hand gently close the choke to the point when I feel a marked resistance. At this time, the gap between the choke and the neck should be about 4 mm. | | 4. If resistance is felt, check the vacuum hoses - there are no cracks in them. | | 5. If the whole hose, pneumatic drive connected to a vacuum gauge and a vacuum pump. Create a vacuum in the actuator 300 mbar. If the actuator is serviceable, the vacuum must not drop within 2 minutes. If the vacuum falls, then the actuator is leaking and must be replaced. |
|
Check pneumatic throttle valve of the second chamber | PERFORMANCE ORDER | | 1. Connect the gauge to the pneumatic drive and vacuum pump. | | 2. Create in the pneumatic vacuum of 50 mbar. If the vacuum does not drop within 2 minutes, the actuator is sealed. Otherwise actuator replaced. |
|
Adjusting the speed of the engine start-up
| 1 - cam air damper;
2 - the screw of adjustment of the speed of the engine start-up |
The adjustment is made in a warm engine with a properly installed and adjusted ignition timing idle speed in the following order:
| PERFORMANCE ORDER | | 1. Remove the air filter and remove the vacuum hose 24 (see. Fig. Air filter engine displacement of 1.1 and 1.3 liters). | | 2. Connect to the engine control tachometer. | | 3. Start the engine and opened the throttle the first chamber until the engine speed about 2500 min -1. | | 4. Rotate the cam until it stops 1. Then turn the throttle valve so that the adjusting screw 2 rested on the second highest ledge. | | 5. Check the tachometer on the control engine speed, it should be 2000 ?� 100 min -1. If the speed is different from the above, adjust the screw 2. |
|
Adjusting the idle speed
Adjustment screws | 1 - the screw of adjustment of quantity of a mixture;
2 - the screw of adjustment of quality (structure) of the mixture;
3 - Heating element;
4 - the electromagnetic valve;
5 - Air damper actuator;
6 - automatic trigger |
The adjustment is made in a warm engine to adjust the clearance in the mechanism of the valve and ignition timing correctly installed in the following order:
| PERFORMANCE ORDER | | 1. Turn off all power consumers (lights, fan, radio and so on. D.). | | 2. Disconnect the hose from the air filter crankcase ventilation and drown him. | | 3. Connect the control tachometer and analyzer. | | 4. Turn cam 1 (see. Fig. Speed control motor starting), so that it does not touch the screw 2. | | 5. adjustment screw 1 to adjust the amount of the mixture speed within 800 ?� 50 min -1. | | 6. The adjustment screw 2 quality (composition) of the mixture to set levels of carbon monoxide (CO) in the exhaust 3,0 ?� 0,5%. Check and, if necessary, to restore the CO content in the exhaust gases. |
