Info
Carry out work with a cold engine.
Water in the float chamber results in malfunctioning.
Info
If there is a big engine speed rise, reduce the idle
speed to a normal level and repeat the above steps.
If the procedure described here does not lead to sat-
isfactory results, the cause may be a wrongly dimen-
sioned idling jet.
If you can turn the idle air adjusting screw to the end
without any change of engine speed, mount a smaller
idling jet.
After changing the jet, start from the beginning with
the adjusting steps.
Following extreme air temperature or altitude changes,
adjust the idle speed again.
Preparatory work

Turn the tap handle of the fuel tap to the OFF position.
Fuel no longer flows from the fuel tank to the carburetor.
