CHECKING THE IGNITION SPARK GAP
1. Check:
• Ignition spark gap
Out of specification  Perform the ignition
system troubleshooting, starting with step (5).
Refer to “TROUBLESHOOTING” on page 8-
5.
TIP
If the ignition spark gap is within specification,
the ignition system circuit is operating normally.

c. Push the ON/start switch and the engine
stop switch to “ ”.
d. Measure the ignition spark gap “a”.
e. Crank the engine by pushing the ON/start
switch and gradually increase the spark
gap until a misfire occurs.
