Spark Plug Inspection and Replacement

Using a non-recommended spark plug can result in serious engine damage. Always use recommended spark plugs.

Note: In order to service the spark plug, the provided spark plug wrench is required.

Refer to the Specification section (see page 64) for the recommended spark plug type. Always torque spark plugs to the 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.
