Static Governor Adjustments
The purpose of making a static governor adjustment
is to remove all free-play between the governor
spool and the carburetor (see illustration). Any free-
play here will result in hunting/surging or erratic
running. After completing this procedure, always
re-check the engine speeds using the steps outlined
in the following pages.
To set the static governor, do the following:
1. Be sure the engine is stopped or damage may
occur.
2. If equipped with a throttle control, place the
throttle in the high speed position.
3. Loosen the governor clamp or screw.
4. Hold the governor arm and link in the W.O.T.
(wide open throttle) position, then rotate the
shaft or shaft/clip assembly in the same direc-
tion and tighten the screw.
5. If engine speed adjustments are needed, follow
the steps described in following pages.
When assembling governor shaft into a flange or cover mounting boss, refer to this chart for exposed shaft
length.
