Governor System

What kind of adjustment should be performed if the carburetor, crankcase cover, or oil sump are removed and reinstalled?

• A static governor adjustment

• A carburetor adjustment

• A fuel line adjustment

• No adjustments are needed

When performing and completing a static governor adjustment on a mechanical governor system, what is the relative position of the flyweights attached to the governor gear compared to the governor cup shaft? What is the relative position of the governor cup compared to the governor shaft?

• The flyweights are fully extended outward away from the governor cup shaft and the cup is fully retracted toward the base of the governor cup shaft

• The flyweights are fully retracted toward the governor cup shaft and the cup is fully retracted toward the base of the governor cup shaft

• Both the flyweights and the governor cup are fully extended away from the governor cup shaft

• The flyweights are fully retracted toward the governor gear shaft and the cup is in the fully extended position away from the base of the governor cup shaft

Which of the following is the most accurate definition of governor droop?

• The decrease in engine speed after the engine begins to stop performing work

• The difference between engine speed at curbed idle and when the speed control is moved to top no load speed.

• The increase in speed before the engine performs work

• Variation in RPM between top no load speed and the maximum power output, or the change in rpms from no load to high load

True or False, Governor springs act against the linkage/linkage spring to help to increase engine speed.

• True

• False

What is the main job of the Governor system?

• maintain a constant rpm or speed

• maintain maximum power input

• maintain maximum fuel efficiency

• none of these

When an engine hits more load what does the governor linkage do to the throttle?

• cracks it slightly

• the linkage doesn't connect to the throttle

• opens it

• closes it

Why do some engines have a governed idle?

• to decrease engine droop

• to make the engine more sensitive

• to make the engine perform more work

• all engines have a governed idle

If a lawnmower with a pneumatic governor seems to increase speed on its own, what is likely to have caused the problem?

• the idle governor gear is disconnected

• a mouse nest or something has clogged the air intake

• A static governor adjustment needs to happen

• the governor springs needs to be tightened

What is the standard rpm for small engines?

• 1500 rpms

• 4200 rpms

• 5400 rpms

• 3600 rpm

If a lawnmower with a mechanical governor seems to increase surging and pulsing in its speed, what is a likely solution to the problem?

• A static governor adjustment needs to happen

• a mouse nest or something has clogged the air intake

• the governor springs needs to be tightened

• the idle governor gear is disconnected
