Replace the spark plug if it is worn or if its reuse is
questionable.

the ground electrode. See Figure 5-5 and
Figure 5-6.

Check for a buildup of dirt and debris around the air
cleaner system. Keep this area clean. Also check for
loose or damaged components. Replace all bent or
damaged air cleaner components.
Note: Operating the engine with loose or damaged air
cleaner components could allow unfiltered air
into the engine causing premature wear and
failure.
