14.5 Cleaning and inspection
Clean all units with clean petrol.
WARNING!
Do not direct the compressed air jet
towards your body or any person when
using compressed air. Air can go
through the skin into the blood and
result in mortal danger
Use compressed air to dry the petrol on the components.
Direct the air through all channels in the carburettor
housing and ensure that they are not blocked.
Do a check of the following:
• That the gasket, pump and control diaphragms are
undamaged, as well as the gasket between the
carburettor body and the autotuner.
• That there is no play on the throttle valve and choke
valve shafts.
• That the needle valve and its lever arm (M) are not
worn. See Figure 12.
• That the fuel screen is intact and clean.
• That the inlet manifold is undamaged.
