Alternator Current Output Reading should be no
less than 30--40V AC above 2000 RPM on each
’leg’.
NOTE: If one or more of the stator leg output AC
voltage varies significantly from the specified value,
the stator may need to be replaced.
TIMING CHECK PROCEDURE
1. The ignition timing check hole is in the starter
recoil/magneto housing. Remove the check plug.
*NOTE: NOTE: The ignition timing marks are
stamped on the outside of the flywheel. Ignition timing
must be inspected with the engine at room
temperature (68°F/20° C).
2. With the transmission in neutral, start the engine
and set engine speed to 5000 ± 200 RPM.
3. Direct the timing light at the ignition timing check
hole and check the ignition timing. NOTE: Do not
allow the engine to warm up. The timing will retard
approximately 2° when the engine is warm.
If the ignition timing is not within the specified range,
adjust the stator plate position as described below.

Stator Adjustment
1. Remove the magneto housing.
2. Remove the flywheel.
3. Loosen the stator plate screws and adjust the
stator plate position. NOTE: Moving the stator
plate clockwise retards (delays) the ignition
timing. Moving the plate counterclockwise
advances it.
