Note: Before you start, see Chapter 2.
Examination
1. When performing this test, fuel must be supplied to the float chamber from a small reservoir.
2. Place the primary chamber over the beaker. Fully open and close the throttle ten times, opening in one second and stopping for three seconds after each reverse. Check that the fast idle cam does not restrict throttle travel on either side.
3. Measure the value of the pumped fuel and compare it with the value determined in Specifications size.
4. If adjustment is needed, loosen the screw and turn the cam plate in the desired direction. Tighten screw and re-check pump performance (see illustration).
Removing
5. Proceed as described in Chapter 17, points 1 and 2.
6. Thoroughly clean the casing of the accelerating pump from the outside.
7. Turn off four screws of fastening, remove a cover of the accelerating pump. Remove diaphragm, spring, spring seat and valve. Note the orientation of the spring seat.
Installation
8. Clean mating surfaces of lid and housing.
9. Check up a condition of the valve, replace if necessary.
10. Position the valve, spring seat, and spring in the casing. Please note that the support can only be installed in one position. The larger diameter spring should face the support.
11. Position the diaphragm on the casing, check that the spring is correctly placed, and install the cover. Tighten the cover fixing screws evenly to avoid diaphragm distortion (see illustration).
12. Further installation is carried out in the reverse order.
