17 TUNING THE ENGINE
103
–
Turn idle air adjusting screw  slowly in a clockwise direction until the idle
speed begins to fall.
–
Note the position and turn the idle air adjusting screw slowly counterclockwise
until the idle speed again begins to fall.
–
Adjust to the point between these two positions with the highest idle speed.
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 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, 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.
