Without Stop Screw).
b. 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-38. Temporarily clamp in
this position.
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-40. It should fall in the center of the
hole. If it doesn’t, perform the adjustment
procedure as follows.
B. Setting the Initial Adjustment
1. Check the split where the clamping screw goes
through the governor lever. See Figure 5B-41.
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.

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.
3. Insert a nail into the hole in the top of the cross
shaft. Using light pressure, rotate the governor
shaft counterclockwise as far as it will turn, then
torque the hex nut on the clamping screw to
6.8 N·m (60 in. lb.) . See Figure 5B-42. Make sure
that the governor arm has not twisted up or
down after the nut has been tightened.

a. On engines without a stop screw, pivot the
throttle shaft and plate assembly into the “Full
Throttle” position. Insert a
1.52 mm (0.060 in.)
feeler gauge between the rear tang of the
throttle shaft plate and the underside of the
manifold boss. Use a locking pliers (needle
nose works best) to temporarily clamp the
parts in this position. See Figure 5B-39.
