Subsection 01 (IGNITION TIMING)
NOTE: When checking timing, certain procedures
require that the magneto flywheel be turned in a
clockwise direction, viewed facing the magneto.
If it is necessary to turn back (counterclockwise)
for any reason, rotate the magneto flywheel at
least one-quarter turn counterclockwise, and then
rotate it clockwise. The last magneto flywheel
movement when making a critical check must al-
ways be in a clockwise direction, 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 TECHNICAL
DATA.
b. Verify that the magneto flywheel mark perfect-
ly 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 ap-
propriate ones and if Woodruff key is in good
condition, continue the procedure.

TYPICAL
1. Trigger coil mark
2. Magneto flywheel mark
NOTE: These marks cannot be used to check dy-
namic (with engine running) ignition timing with a
timing light: a new mark must be scribed on mag-
neto flywheel for this purpose.
– Scribe a new mark on magneto flywheel as fol-
lows.
• Remove the fan cover from the engine.
• Maintain magneto flywheel so that previous
marks remain aligned.
• Scribe or punch a mark on magneto flywheel
so that it perfectly aligns with the arrow on
crankcase, refer to illustration. This new tim-
ingmarkshouldbeusedforfuturetiming
checks (dynamic timing).
• Reinstall rewind starter.
• Check the timing with a timing light.

Checking Ignition Timing
Use a timing light and digital induction type
tachometer (P/N 529 014 500).
