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
8-4.
If the ignition spark gap is within specification,
the ignition system circuit is operating normally.

a. Remove the ignition coil from the spark plug.
b. Connect the ignition checker “1” as shown.
c. Turn the main switch to “ON”.
d. Measure the ignition spark gap “a”.
e. Crank the engine by pushing the “ ” side of
the start/engine stop switch and gradually in-
crease the spark gap until a misfire occurs.
