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
Each step from number to number or from letter to letter on the governor lever arm represents a change of ______________ rpms.
30
60
100
15
Why is it important to replace any spring on an engine with the exact same kind (length, tension, size, etc)?
its not important, a spring is a spring
replacing a spring with a larger spring will increase speed
replacing a spring with a larger spring will decrease speed
each spring is designed for a specific job
What is a governor of a small engine like on a car?
the EFI
the brakes
cruise control
the fuel pump
What closes the throttle on a pneumatic governor?
governor air vane
governor spring
throttle plate linkage
gravity
What opens the throttle on a pneumatic governor?
governor air vane
gravity
governor spring
throttle plate linkage
What closes the throttle on a mechanical governor?
Throttle plate linkage and spring
Governor Spring
Idle Spring
centrifugal force
What opens the throttle on a mechanical governor?
Idle Spring
Centrifugal force
Throttle plate linkage and spring
Governor spring
If the governor spring is increased the engine will___________?
Speed up
Slow down
remain the same
use less gas
If air cannot get out of a pneumatic governor, what happens to the speed?
Increases
Decreases
Nothing
Remains the same
Mechanical Governors act on totally different principles than Pneumatic Governors, true or false?
True
False
What are 2 advantages of a mechanical governor?
more sensitive
quicker adjustment time
cheaper
easier to work on and replace
How do the flyweights open up on the governor gear?
Idle Spring
Governor Spring
Throttle plate linkage and spring
Centrifugal force
