Servicing the Spark Plugs
WARNING
Unintentional sparking can result in fire or electric
shock.
Unintentional start-up can result in entanglement,
traumatic amputation, or laceration.
When testing for spark:
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.
CAUTION: Spark plugs have different heat ranges. It is
important that the correct spark plug is used, otherwise,
engine damage can occur.
Check Spark Plug Gap
Use a spark plug feeler gauge to check the gap between the
two electrodes. When the gap is correct, the gauge will drag
slightly as you pull it through the gap.
If necessary, use the spark plug gauge to adjust the gap by
gently bending the curved electrode without touching the
center electrode or the porcelain.
