Checking the Spark Plug
Air Gap:
0.6 to 0.7 mm (0.02 to 0.03 inch)
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.
Use a gapping tool/feeler gauge to check and adjust
the air gap to 0.6 to 0.7 mm (0.02 to 0.03 inch).
