Sensitivity Adjustment

A Governor Lever B Hole 1

C Hole 2 D Hole 3

E Hole 4

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).
