5. Release throttle arm, loosen jam nut on governor low
idle stop screw and adjust it to get 1500 ± 100 rpm.
Tighten jam nut.
6.
Slowly move throttle to FAST position until engine
speed reaches 3200 ± 100 rpm. Shut off engine. Adjust
high idle stop screw until it contacts speed control lever.
IMPORTANT: Do not over-speed the engine because
the transmission could be damaged.
7. Move throttle rapidly from SLOW to FAST. The engine
should not surge. If engine surges, go to step 8.
8.
Check V-belts from engine to governor pulley and
make sure they are tight. If belts are loose, engine will
surge. If belts are tensioned properly, loosen jam nut
that retains anti-surge screw. Rotate screw clockwise
1/8 turn at a time until surging stops. Should governor
continue to surge, check the following:
Figure 4
1. High idle stop screw
2. Speed control lever
3. Jam nut
5. Oil check plug
6. Low idle stop screw
7. Oil fill plug
A. Carburetor too rich or too lean.
B. Binding in throttle linkage.
C. Governor worn internally.
4. Anti-surge screw
IMPORTANT: Never rotate anti-surge screw in too
far so that speed of engine increases.
9. Bump throttle lever with your hand so engine speeds
up momentarily. If governor is working properly, engine
speed should return to normal within one or two surges
of governor. More than two surges of governor usually
indicates that the anti-surge screw must be turned in
slightly more than it is. When adjustment is correct, lock
jam nut against governor body.
10. Check low and high idle speed to be sure there is
no change from initial setting. If high idle speed has
increased, anti-surge screw has been turned into gov•
ernor too far and it must be backed out. Then, repeat
the entire adjustment procedure.
NOTE: If the throttle control on instrument panel will not
stay in FAST position during operation, remove panel
cover and tighten nut and capscrew at base of throttle
lever assembly.
