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
8-7.
Minimum ignition spark gap
6.0 mm (0.24 in)
TIP
If the ignition spark gap is within specification,
the ignition system circuit is operating normally.
