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: CR8E
Measure the spark plug gap between the
