With the engine at normal operating temperature, operate the engine at wide open throttle and compare the rpm
with the operating range which is stamped on the governor plate. In no case is the engine rpm to exceed 2800 rpm.
If adjustment is required, remove the seal attached to the governor adjusting cap. Turn the cap counterclockwise
to increase rpm, clockwise to decrease rpm. When the adjustment is completed, stop the engine and reattach the seal.
CYLINDER HEAD BOLT TORQUE
The cylinder head bolts are tightened in three progressive steps, starting with the center bolts and working
outward. Torque the bolts to 50-55 ft-lbs then to 60-65 ft-lbs and finally to 70-75 ft-lbs.
Torque the cylinder head bolts before starting your engine and also after the engine has been warmed up to
normal operating temperature.
