Pressure testing the carburettor

Pressure testing should be carried out with the car- burettor fully assembled. Testing should always be carried out after the carburettor has been repaired, but it can also be carried out as trouble shooting before dismantling the carburettor.

See figure and carry out the test as follows:

1

Set the high and low jet screws two turns from the bottom.

2

Connect pressure tester to the carburettor’s fuel intake.

3

Lower the carburettor into a beaker of water (see figure 37).

4

Pump the pressure up to 50 kPa.
