The governor spring wants to __________ the throttle?
The governor arm wants to ___________ the throttle
What is the main purpose of the governor system?
Maintain a desired engine speed for maximum power and torque
Decrease engine speed when the engine is under a load
I don’t know
Increase engine speed under a no-load condition
Under a load most engines will __________?
Produce more torque
The governed speed of an engine is the speed obtained at the balance point between the forces of the speed-sensing device and the governor spring.
What is the function of the throttle plate?
Regulate the amount of air/fuel into combustion chamber during engine operation.
Acts as a speed sensing device to regulate engine speed.
Creates a rich fuel environment during cold engine starting
Regulates the amount of pressure in the cylinder head
A _____ governor system is a system which uses force from moving air produced by rotating flywheel fins to sense engine speed.
A(n) _____ system is a system that maintains a desired engine speed regardless of the load applied to the engine.
A(n) _____ governor system is a governor system that uses a gear assembly that meshes with the camshaft or other engine components to sense and maintain the desired engine speed.
Governor systems limit the amount of horsepower available by controlling engine ______.

C. governor spring
What is the function of this part? Select all that apply:
Oil slinger which lubricates the internal parts of the engine
Speed sensing device to help control engine speed
An oil pump which lubricates the internal parts of the engine
A timing device which keeps the camshaft and crankshaft in time
What holds the throttle shaft in the idle position?
Speed sensing component
Governed Idle Spring
No damage can occur from an engine with the incorrect speed setting.
Some Briggs & Stratton governor systems feature a governed idle spring. What performance benefit does this feature provide?
Keeps the engine from over heating
Allows the user to apply a full load to the engine
Accept light to medium loads at slower or idle throttle positions
Run for a long life
What symptom will be exhibited on an engine equipped with a pneumatic governor system if the cooling fins are plugged?
Engine speed will rise
Engine performance has slow response
Engine performance can respond faster to a load
The RPM decreases
