Spark Plugs
1. Normal
The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This
indicates the proper type and heat range for the engine and the service.
NOTE:
The tip should not be white. A white insulator tip indicates
overheating, caused by use of an improper spark plug or incor-
rect carburetor/throttle body adjustments.
2. Wet Fouled
The wet fouled insulator tip is black. A damp oil film covers the firing
end. There may be a carbon layer over the entire nose. Generally, the
electrodes are not worn. General causes of fouling are excessive oil, use
of non-recommended injection oil, improper use of the choke, or incor-
rect carburetion adjustments.
Spark Plug Removal and Replacement
1. Remove the spark plug cap.
2. Using the special wrench provided in
the tool pouch, rotate the spark plug
counterclockwise to remove.
3. Reverse the procedure for spark plug
installation.
4. Torque the spark plug to specification.
5. Reinstall the spark plug cap.
