OHV V-Twin engines may be equipped
for remote control, manual friction, or fixed speed
adjustable governor controls.
Remote Control and Manual Friction
Remote governor controls (supplied by the OEM)
and manual friction governors (mounted on the
engine) control engine speed by increasing or
decreasing tension on the governor spring(s) to
obtain the desired engine speed. Both controls,
Fig. 1 , provide speed control at all positions.

Fixed Speed Adjustable
The fixed speed adjustable governor, Fig. 2 is used
in applications where a constant speed is required,
such as generator applications.

Governed Idle
OHV V-Twin engines equipped for manual friction or
remote control have a governed idle system,
Fig. 3 .
A throttle restrictor maintains the engine speed
when a load is applied and the equipment control is
in the SLOW position.

GOVERNOR CONTROLS
Remote Control Wire Travel
In order to make proper remote control adjustments,
the remote control wire must have travel of
not less
than 1-3/8” (35 mm) (2) with controls mounted in
equipment, Fig. 4 . The dimension from the end of
the cable casing to the wire at the end of its travel (1)
is
2-1/8” (54 mm) minimum .
Some control brackets are equipped with a plastic
swivel for the control wire. The control wire has a 90º
bend and snaps into the swivel. The length of the
bend (3) should not exceed
