Governor System
14 690 12 Rev. -- KohlerEngines.com
● When engine is at rest, and throttle is in fast position,
tension of governor spring holds throttle plate open.
When engine is operating, governor gear assembly is
rotating. Force applied by regulating pin against cross
shaft tends to close throttle plate. Governor spring
tension and force applied by regulating pin balance
each other during operation, to maintain engine
speed.
● When load is applied and engine speed and governor
gear speed decreases, governor spring tension moves
governor arm to open throttle plate wider. This allows
more fuel into engine, increasing engine speed. As
speed reaches governed setting, governor spring
tension and force applied by regulating pin will again
off set each other to hold a steady engine speed.
Initial Governor Adjustment
Make this initial adjustment whenever governor arm is
loosened or removed from cross shaft. To ensure proper
adjustment, make sure throttle linkage is connected to
both governor arm and throttle lever on carburetor.
1. Loosen nut holding governor lever to cross shaft.
2. Move governor lever away from carburetor (wide
open throttle) and hold in this position. Do not apply
excess force that may fl ex or distort throttle link.
3. Grasp cross shaft with a pliers and turn shaft
clockwise as far as it will go, hold and tighten nut.
Then torque nut to 9.5 N·m (84 in. lb.).
