Servicing the Spark Plug

Make sure the air gap between the center and side electrodes

Install a new spark plug(s) if necessary.

Removing the Spark Plug

Checking the Spark Plug
Important:
Never clean the spark plug(s). Always
replace the spark plug(s) when it has: a black coating,
worn electrodes, an oily film, or cracks.
If you see light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator usually
means the air cleaner is dirty.
Set the gap to 0.030 inches (0.75 mm).
