Note: In order to service the spark plug, a commercially available spark plug wrench is required.
Refer to the “Specification” (page 62) for the recommended spark plug type. Always torque the spark plug to specification.
Note: To ensure proper engine operation, the spark plug must be free of deposits and properly gapped. If the engine has been running, allow it to cool before servicing.
Normal Spark Plug
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, fuel, or incorrect carburetor adjustments.
Wet Fouled Spark Plug
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. Fouling may be caused by excessive oil or by frequent short trips, especially in cold weather.
