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-30 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.

2. Pivot the throttle shaft and plate into the "Full
Throttle" position, so the tang of the throttle
shaft plate is against the manifold casting. See
Figure 5B-31. Temporarily clamp in this position.
Figure 5B-31. Clamping Throttle Against Stop.
3. Rotate the governor lever and shaft
counterclockwise until it stops. Use only enough
pressure to hold it in that position.
4. Check how the end of the throttle linkage aligns
with the bushing hole in the governor lever. See
Figure 5B-32. It should fall in the center of the
hole. If it doesn't, perform the adjustment
procedure as follows.
Figure 5B-32. Throttle Link in Center of Hole.
B. Setting The Initial Adjustment
1. Check the split where the clamping screw goes
through the governor lever. See Figure 5B-33.
There should be a gap of at least 1/32". If the tips
are touching and there is no gap present, the
lever should be replaced. If not already installed,
position the governor lever on the cross shaft,
but leave the clamping screw loose.
Figure 5B-33. Checking ''Split'' of Clamp.
2. Follow the instructions in Step 2 of ''Checking
the Initial Adjustment,'' then reattach the
throttle linkage to the governor lever with the
bushing clip. It is not necessary to reattach the
damper or governor springs at this time.
