Checking the Spark Plugs
1. Look at the center of both spark plugs ( Figure 41 ). 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.
Important:
Never clean the spark plugs. Always
replace the spark plugs when they have a black
coating, worn electrodes, an oily film, or cracks.

(

3. Bend the side electrode ( Figure 41 ) if the gap is not
correct.

2. Tighten the spark plugs to 27 N∙m (20 ft-lb).
