tion 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 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 idling jet, start from the beginning
with the adjusting steps.
Following extreme air temperature or altitude changes,
adjust the idle speed again.
