Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 28). 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.
Important
Never clean the spark plug(s). Always
replace the spark plug(s) when it has: a black coating,
worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 28). Bend the side electrode (Fig. 28) if the gap is
not correct.
