Checking the Spark Plugs
1. Look at the center of the spark plugs (Fig. 42). 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 plugs. Always
replace the spark plugs when it has a black coating, worn
electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 42). Bend the side electrode (Fig. 42) if the gap is
not correct.
