● 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
offset 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 governor lever adjustment screw.
2. Move governor lever away from carburetor (wide
open throttle). Do not apply excess force that may
ex or distort throttle link.
3. Grasp cross shaft with a pliers and turn shaft
clockwise as far as it will go. Then torque nut to
9.5 N·m (84 in. lb.).
4. Rotate governor shaft clockwise until it stops.
5. Hold both in this position and torque governor lever
bolt to 10 N·m (88.5 in. lb.).
