Info
If the speed rise is too high, reduce the idle speed to a normal level and
repeat the preceding 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 adjusting screw to the end without any change of
engine speed, you have to install a smaller idling jet.
After changing the idling jet, start from the beginning with the adjusting
steps.
