Engine Speed Adjustments
Adjustments to the engine speed settings are not nor-
mally necessary unless the throttle linkage, injection
pump, or governor mechanism have been repaired,
rebuilt, replaced or are not operating correctly.
Since there is no igni
tion system from which to power
an electronic tachometer, a vibration-type tachometer
must be used to set engine speed.

The high speed set bolt has been set properly and
sealed at the factory. Never tamper with the seal unless
necessary.

Idle Speed Adjustment

engine.

su
re the parking brake is engaged.
