Inspection
Inspect the governor gear teeth. Look for any evidence
of worn, chipped, or cracked teeth. If one or more of
these problems is noted, replace the governor gear.
The gear is held on the governor sha by molded tabs,

reuse the gear once it has been pulled from the sha.
Replace the governor sha only if it is damaged or
worn.
