I advise that every purchaser of an agricultural motor read his instruction book with care, that is, locate all oil holes and note the action and purpose of every part. If in doubt as to any part of its use write the manufacturer of the motor.
(132) Throttling Governor Troubles.
STICKING GOVERNOR VALVE will cause the engine to overspeed; remove the gum and dirt.
LOOSE PINS OR BUSHINGS, or lost motion in any part of the governor mechanism will cause irregular motion or running; be sure that the bearings and joints are well oiled.
STUCK PINS will cause the engine to overspeed on light loads, and fall down on the normal load, or cause racing.
WEAK OR BROKEN SPRINGS will cause the engine to lose speed or to lie down altogether even on light loads.
STIFF GOVERNOR SPRINGS cause the engine to speed up.
SLIDING COLLAR stuck will cause racing or a fluctuation in the speed. Keep the governor well oiled, clean, and free from gum.
The governing valve should be removed from its care frequently and thoroughly cleaned with kerosene. Deposits of carbon and gummed oil at this point are dangerous because of the likelihood of their causing overspeeding.
