Idle Speed Adjustment
Perform this adjustment if the idle is slow
or rough, and you're sure the air filter and
spark plug are in good condition. You
must have an accurate tachometer to
properly measure engine speed.
1. Start the engine in an area with
adequate ventilation to avoid carbon
monoxide poisoning. Allow the engine
to warm to normal operating
temperature.
2.
With the throttle on
SLOW,
turn the
throttle stop screw in or out to obtain
the specified idle speed.
