Initial Governor Adjustment

The initial governor adjustment is especially critical

on EFI engines because of the accuracy and sensitivity

of the electronic control system. Incorrect adjustment

can result in overspeed, loss of power, lack of

response, or inadequate load compensation. If you

encounter any of these symptoms and suspect them to

be related to the governor setting, the following

should be used to check and/or adjust the governor

and throttle linkage.

If the governor/throttle components are all intact, but

you think there may be a problem with the

adjustment, follow Procedure A to check the setting. If

the governor lever was loosened or removed, go

immediately to Procedure B to perform the initial

adjustment.

A. Checking the Initial Adjustment

1. Unsnap the plastic linkage bushing attaching the

throttle linkage to the governor lever. See Figure

5B-34. Unhook the damper spring from the lever,

separate the linkage from the bushing, and

remove the bushing from the lever. Mark the hole

position and unhook the governor spring from

the governor lever.

Figure 5B-35. Throttle Details.

a. On engines with a stop screw, pivot the

throttle shaft and plate into the “Full Throttle”

position, so the tang of the throttle shaft plate

is against the end of the high-speed stop

screw. See Figure 5B-35. Temporarily clamp in

this position.
