NOTES
Keep the following notes in mindwhen diagnosingan
electrical problem.
GRefer to wiring diagram for stator and
electrical component resistance
specifications.
GWhen measuring resistance of a
component that has a low resistance
value (under10 Ohms), rememberto
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, amper age, and r esis t ance
values inc luded in this manual are
obtained with a F luk et 77 Digit al
Multim et er (PV--43568).This
met er is ac cept able f or use when
diagnosing elect ric al problem s.
Readings obtained with other
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/magnetohousing. Removethecheckplug.
NOTE: Theignitiontimingmarks arestampedonthe
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
holeand checktheignitiontiming. NOTE: Donot
allowtheenginetowarmup. Thetimingwillretard
approximately 2° when the engine is warm.

Stator Adjustment
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.
