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.
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 0.75 mm (0.03 inch).
