Governor sensitivity is adjusted by repositioning
governor spring in holes of governor lever. If speed
surging occurs with a change in engine load, governor
is set too sensitive. If a big drop in speed occurs when
normal load is applied, governor should be set for
greater sensitivity. Adjust as follows:
1. To increase sensitivity, move spring closer to
governor lever pivot point.
2. To decrease sensitivity, move spring away from
governor lever pivot point.
Testing Engine
It is recommended engine be operated on a stand or
bench prior to installation in piece of equipment.
1. Start engine, inspect for leaks and check to make
certain that oil pressure (20 psi or more) is present.
Run engine at idle for 2-3 minutes, then 5-6 minutes
more between idle and midrange.
2. Adjust idle speed screw located on throttle body as
necessary. Standard idle speed setting for EFI
engines is 1500 RPM, but certain applications might
require a diff erent setting.
3. Adjust high-speed stop as necessary located on
control panel (if equipped). Make sure maximum
engine speed does not exceed 4200 RPM (no load).
