Section 5
Fuel System and Governor
Adjustments
General
The governed speed setting is determined by the
position of the throttle control. It can be variable or
constant, depending on the engine application.
Figure 5-36. Governor Controls and Linkage
(External).
Initial Adjustment
NOTE: EFI engines require a special initial
adjustment procedure, which is covered in
subsection 5B. Refer to "Initial Governor
Adjustment" in that section for setting the
governor on EFI-equipped engines.
Procedure - Carburetor Equipped Engines
Make this adjustment whenever the governor arm is
loosened or removed from the cross shaft. See Figure
5-36 and adjust as follows:
1. Make sure the throttle linkage is connected to the
governor lever and the throttle lever on the
carburetor.
2. Loosen the hex. nut holding the governor lever to
the cross shaft.
3. Move the governor lever toward the carburetor as
far as it will move (wide-open throttle) and hold in
position.
4. Insert a nail into the hole in the end of the cross
shaft and rotate the shaft counterclockwise as
far as it will turn, then tighten the hex. nut
securely.

Sensitivity Adjustment
Governor sensitivity is adjusted by repositioning the
governor spring in the holes of the governor lever. If
speed surging occurs with a change in engine load,
the governor is set too sensitive. If a big drop in speed
occurs when normal load is applied, the governor
should be set for greater sensitivity. See Figure 5-37
and adjust as follows:
1. To increase the sensitivity, move the spring closer
to the governor lever pivot point.
2. To decrease the sensitivity, move the spring away
from the governor lever pivot point.
High Speed (RPM) Adjustment (Refer to Figures
5-37 or 5-38.)
1. With the engine running, move the throttle control
to fast. Use a tachometer to check the RPM
speed.
2. Loosen the lock nut on the high speed adjusting
screw. Turn the screw counterclockwise to
decrease, or clockwise to increase RPM speed.
Check RPM with a tachometer.
3. When the desired RPM speed is obtained,
retighten the lock nut.
NOTE: When the throttle and choke control cables

are routed side-by-side, especially under a
single clamp, there must be a small gap
between the cables to prevent internal
binding. After the high-speed setting has been
completed, check that there is a gap of at
least 0.5 mm (0.020 in.) between the control
cables.
