Checking the Spark Plug
Important:
Replace the spark plug(s) when it
has: a black coating, worn electrodes, an oily film,
cracks or reuse is questionable.
If you see light brown or gray on the insulator, the
engine is operating properly. A black coating on the
insulator usually means that the air cleaner is dirty.
Set the gap to 0.76 mm (0.030 inches).
