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.
Set the gap to 0.76 mm (0.03 inch).
