Repair instructions
Carburettor – pressure testing
Carburettor – refitting
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 can also be performed for troubleshooting
before dismantling.
NOTE!
Cleanliness is very important when reas-
sembling the carburettor. Tiny particles of
dirt can cause operating problems.

tor flange and the insulating plate.
