6.18. Accelerating pump


Adjustment of productivity of the accelerating pump, "+" to increase ", -" to reduce

1. At check of operability of the accelerating pump it is necessary to submit to the poplavkovy chamber fuel from the additional tank.
2. Establish the primary chamber of the carburetor over a volumetric glass. Ten times completely open and close a throttle a ny zaslonka, and opening of a zaslonka make within one second then return a zaslonka to a starting position and in three seconds repeatedly open it. Check, that the cam of the accelerated turns of idling did not limit butterfly valve moving.
3. Measure amount of fuel which the accelerating pump submitted to a volumetric glass, and compare these data with technically ми characteristics.
4. If adjustment is required, weaken the screw of fastening and turn a cam in the demanded direction then tighten the screw and repeatedly check productivity of the accelerating pump (see fig. Adjustment of productivity of the accelerating pump).


1. Remove a weight wire from the accumulator.
2. On early models remove the air filter. On later models disconnect an air pipe from the air filter, then disconnect a vacuum pipe and a hose of ventilation of a case from the air chamber. Unscrew three screws and remove the air chamber together with an air line.
3. Clear an external surface of the accelerating pump.
4. Unscrew four screws and uncover the accelerating pump, a diaphragm, a spring, a support of a spring and the valve.


Elements of the accelerating pump

1–a cover with a control lever;
5–an opening for air

1. Clear interfaced surfaces of a cover of the accelerating pump and the carburetor case.
2. Check a condition of the valve of the accelerating pump and, if necessary, replace it.
3. Establish the valve, a support of a spring and a spring in the carburetor case. In big diameter the spring should be направле on to the carburetor.
4. Establish in the carburetor case a diaphragm and a cover of the accelerating pump. Gradually and evenly screw up screws of fastening of a cover of the accelerating pump not to deform a diaphragm (see fig. Elements of the accelerating pump).
5. Further installation is made in sequence, return to removal.
