Checking the Spark Plug
Important:
Do not clean the spark plug(s).
Always replace the spark plug(s) when it has: a
black coating, worn electrodes, an oily film, or
cracks.
Note:
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.
