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).
Installing the Spark Plug
Tighten the spark plug(s) to 24.4 to 29.8 N-m (18 to
22 ft-lb).
