GENERAL INFORMATION

The purpose of the mechanical governor is to maintain,
within certain limits, a desired engine speed, even
though loads may vary. The governor spring tends to pull
the throttle open. The force of the flyweights, which are
operated by centrifugal force, tends to close the throttle.
The engine speed at which these two forces balance is
called the governed speed. The governed speed can be
varied by changing governor spring tension. If a
governor spring must be replaced, consult the
appropriate Illustrated Parts List. Select the proper
governor springs by engine type number.
NOTE
: After a new governor spring is installed,
check engine top governed speed with an
accurate tachometer.

REMOTE GOVERNOR CONTROLS

VanguardE liquid cooled OHV Twin cylinder engines are
equipped for remote governor controls, Fig. 181.
Speed Regulation
Remote governor controls (supplied by equipment
manufacturer) control engine speed by increasing or
decreasing tension on governor spring(s) to obtain
desired engine speed at all positions.
Fig. 181
Governed Idle
VanguardE liquid cooled OHV Twin cylinder engines are
equipped with a governed idle system, Fig. 182. A
throttle restrictor permits the engine to maintain
engine speed when a load is applied with the equipment
control in the SLOW position.
