Disconnect the spark plug cap and clean
around the spark plug.
Remove the spark plug using a equipped
spark plug wrench or an equivalent tool.
Inspect or replace as described in the
maintenance schedule.
INSPECTION
Remove the carbon deposits from the spark
plug with a small wire brush or a spark plug
cleaning machine.
The spark plug should be replaced
periodically. Whenever removing the
carbon deposits, be sure to observe the
operational color of the spark plug's
porcelain tip. This color tells you whether or
not the standard spark plug is suitable for
your type of usage. A normal operating
spark plug should be light brown or tan
color. If the spark plug is very white or
glazed appearing, then it has been operating
much too hot. This spark plug should be
replaced with the colder plug.
Recommended spark plug: NGK: CR7E
Ignition Coil Cap
