15 TUNING THE ENGINE 77
Info
If the engine speed rises considerably, reduce the idle speed to a normal
level and repeat the above steps.
If the procedure described here does not lead to satisfactory results, the
cause may be a wrongly dimensioned idling jet.
If you can turn the idle air adjusting screw to the end without any change of
engine speed, you need to install a smaller idling jet.
After changing the idling jet, start from the beginning with the adjusting
steps.
Following extreme air temperature or altitude changes, adjust the idle speed
again.
