NOTES
Keep the following notes in mind when diagnosing an
electrical problem.
GRefer to wiring diagram for stator and
electrical component
specifications.
GWhen measuring resistance of a
component that has a low resistance
value (under10 Ohms), remember to
subtract meter lead resistance from
the reading. Connect the leads
together and record the resistance.
The resistance of the component is
equal to tested value minus the lead
resistance.
GBecome familiar with the operation of
your meter. Be sure leads are in the
proper jack for the test being
performed (i.e. 10A jack for current
readings). Refer to the Owner's
manual included with your meter for
more information.
GVoltage, amperage, and resistance
values included in this manual are
obtained with a Fluket 77 Digital
Multimeter (PV- -43568).
meter is acceptable for use when
diagnosing electrical
Readings obtained
meters may differ.
GPay attention to the prefix on the
multimeter reading (K, M, etc.) and
the position of the decimal point.
GFor resistance readings, isolate the
component to be tested. Disconnect
it from the wiring harness or power
supply.

TIMING CHECK PROCEDURE
1. The ignition timing check hole is in the starter
recoil/magneto housing. Remove the check plug.
NOTE: The ignition timing marks are stamped on the
outside of the flywheel.
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.

Stator Adjustment
If the ignition timing is not within the specified range,
adjust the stator plate position as described below.
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.
