Adjusting the level of fuel in the float chamber
Checking the position of the float carburetor 32TLA | 1 - a cover of the carburettor;
2 - float;
3 - the main fuel jet;
A - the size of the plane of the lid to the bottom edge of the carburetor float |
Adjust the position of the fuel level float. To check the position of the float carburetor and remove the cover to install it at an angle of 45 ?° to the horizontal. Measure the size of the "A". This size should be equal to 28 ?± 1,0 mm. If the measured size differs from specified, bend the float.
Adjusting the accelerator pump
Adjusting the accelerator pump | 1 - adjustment screw priotkryvaniya throttle;
2 - the throttle lever;
3 - a nut;
4 - Screwdriver;
5 - the cam drive of the accelerating pump;
6 - screw |
To check and adjust the performance of the accelerator pump is necessary to remove the carburetor from the engine.
| PERFORMANCE ORDER | | 1. Remove the cover 47 (see. Fig. Details 32TLA carburetor Weber). | | 2. Remove the three screws and remove the ring 46, the cover 45 of the automatic starting device 44 and the heating element. | | 3. Pull the elastic arm 3 (Fig. 3.21 Adjusting the speed of the engine start-up) so that cam 2 came out of contact with the adjusting screw 1. | | 4. Remove the cover of the carburetor float chamber filled with fuel and set the carburettor cover. | | 5. Put a carburetor measuring beaker with a funnel. | | 6. Slowly turn the throttle valve from stop to stop 10 times, spending each turn 1, and then sustaining a pause in 3 seconds, resulting in this action the accelerating pump. | | 7. 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 equal to 1,05 ?± 0,15 cm 3. | | 8. If necessary, adjust the performance of the accelerator pump. To do this, tighten the screw 6. Remove the clip and loosen the nut 3. Loosen the screw with a screwdriver and turn the 2 cam 5. Turn the cam 5 in the direction of "" increases the productivity of the accelerating pump, and in the direction of "-" - reduces. 3 Tighten the nut and install the lock. |

Adjusting the throttle priotkryvaniya
Adjusting the speed of the engine start-up
Adjusting the speed of the engine start-up | 1 - the screw speed control motor starting;
2 - the cam;
3 - the lever of the starting device;
4 - gum |
The adjustment is made in a warm engine with a correctly set ignition timing and adjust the frequency of rotation of idling 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. Remove the lid 47 (see. Fig. Details 32TLA carburetor Weber), 45 and the heating element 44. | | 4. Set the adjusting screw 1 on the cam lobe 2. | | 5. Pull lever 3 rubber band 4 to the air damper has fully opened. | | 6. Start the engine without using the accelerator pedal. | | 7. tachometer to check engine speed, it should be 2000 ?± 100 min -1. If necessary, adjust the speed of the motor rotor 1. |
|
Adjusting the idle speed
The adjustment is made in a warm engine to adjust the clearance in the mechanism of the valve, and when properly prescribed point of ignition at full choke in the following order:
| PERFORMANCE ORDER | | 1. Turn off all power consumers (lights, fans, radio, etc.). | | 2. Disconnect the hose from the air filter crankcase ventilation and drown him. | | 3. Connect the control tachometer and analyzer. | | 4. The adjustment screw 15 (see. Fig. Details 32TLA carburetor Weber) the amount of the mixture to adjust the engine speed within 800 ?± 50 min -1. |  | 5. adjustment screw 1 quality (composition) of the mixture to set levels of carbon monoxide (CO) in the exhaust 2,0 ?± 0,5%. | | 6. Check and, if necessary, to restore the idle speed. Check and, if necessary, to restore the CO content in the exhaust gases. |
|
Adjusting the choke gap | 1 - cam;
2 - the screw of adjustment of the speed of the engine start-up;
3 - pull the choke actuator |
| PERFORMANCE ORDER | | 1. Remove the cover 47 (see. Fig. Details 32TLA carburetor Weber), 45 and 44 element. | | 2. Adjustment screw 2 set on the top ledge of the cam 1. | | 3. Move the screwdriver rod 3 in the direction of the arrow. |  | 4. Measure the gap between the air valve and the wall of the throat, it must be 2, 5 ?± 0.2 mm. At the same time pay attention to not compressed spring 2. The gap can be measured drill 1 suitable diameter. If the backlash differs from specified, adjust the screw 3. |
