Section 06 ELECTRICAL
Sub-Section 02 (IGNITION TIMING)
06-02-5
NOTE : When checking timing, certain pro-
cedures require that the magneto flywheel
be turned in a clockwise direction, viewed facing
the magneto /generator. If it is necessary to turn
back (counterclockwise) for any reason, rotate the
magneto flywheel at least one-quarter turn coun-
terclockwise, and then rotate it clockwise. The
last magneto flywheel movement when making a
critical check must always be in a clockwise direc-
tion, to ensure that the slack in engine moving
parts is taken-up.
a. Rotate the magneto flywheel counterclock-
wise, one-quarter turn then carefully rotate it
clockwise until the needle indicates the
specified measurement. Refer to 10 TECH-
NICAL DATA.
b. Verify that the magneto flywheel mark per-
fectly aligns with the mark on the trigger coil,
refer to illustration.
c. If the marks do not align, check magneto fly-
wheel and trigger coil part numbers and
check Woodruff key condition. If all parts are
the appropriate ones and if Woodruff key is
in good condition, continue the procedure.
1. Trigger coil mark
2. Magneto flywheel mark
NOTE : These marks can not be used to
check dynamic (with engine running) ignition
timing with a timing light : a new mark must be
scribed on magneto flywheel for this purpose.
6. Scribe a new mark on magneto flywheel as fol-
lows.
a. Remove the fan cover from the engine.
b. Maintain magneto flywheel so that previous
marks remain aligned.
c. Scribe or punch a mark on magneto flywheel
so that it perfectly aligns with the arrow on
crankcase, refer to illustration. This new tim-
ing mark should be used for future timing
checks (dynamic timing).
d. Reinstall rewind starter.
e. Check the timing with a timing light.
1. Crankcase arrow
2. Scribe a mark here
3. Maintain verified timing marks aligned (static timing)
Checking Ignition Timing
Use timing light (P / N 529 0092 00).
To check the ignition timing, refer to illustration
and proceed as follows :
NOTE : Engine should be cold when check-
ing timing. Do not idle engine for more than
20 seconds and make checks quickly.
WARNING : Place ski tips against a wall,
raise rear of vehicle on a stand, so that
track does not contact the ground. Do not al-
low anyone in front of or behind the vehicle
while engine is running. Keep clear of track
and do not wear loose clothing which can get
caught in moving parts.
