Governor Lever
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 10-95
and adjust as follows:
Figure 10-95. Governor Lever.
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.
Testing the Engine
It is recommended that the engine be operated on a
test stand or bench prior to installation in the piece of
equipment.
1. Set the engine up on a test stand. Start engine,
inspect for leaks and check to make certain that
oil pressure (20 psi or more) is present. Run the
engine at idle for 2-3 minutes, then 5-6 minutes
more between idle and midrange.
2. Adjust the idle speed screw located on the
thro le body as necessary. The standard idle
speed se ing for EFI engines is 1500 RPM, but
certain applications might require a diff erent
se ing.
3. Adjust the high-speed stop as necessary located
on the control panel (if so equipped). Make sure
the maximum engine speed does not exceed 4200
RPM (no load).
