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 with-

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.
