Like the mechanical type, it will incorporate the use of one or two springs, which pulls it in an open position. When the load becomes less and the speed of the engine increases, the air that enters the flywheel will also increase.
That leads to the governor blade pulling the throttle forward and close it, so that the engine remains in a steady speed limit. This is a fully automated system , which consists of a stepper motor, a controller, and a magnetic pick up in some cases. The pick-up will signal to the controller regarding the speed of the engine, and will also regulate the opening and closing of the throttle — resulting in the increase or decrease of speed respectively.
Note that some electronic systems will leave the controller to read the sparks and their frequency, which allows it to know the engine speed. This is particularly in case when the system does not have a magnetic pick up.
Knowing the state of your governor is very important to controlling your lawn mower and its level of efficiency. This will also help you to detect problems with the working mechanism early on, and find solutions to it as soon as possible to restore your engine.

Tighten the idle adjustment screw, found on the side of the carburetor, by turning it clockwise just to the point where you feel it lightly touching the seat of the carburetor.
What are the types of governors? These governors consist of weighted balls, or flyweights, that experience a centrifugal force when rotated by the action of the engine crankshaft. Hydraulic governors. Electro-Hydraulic governors. Flyweight Assembly. Hydraulic Control.
Governor sensitivity. Electronic System. Maintenance of Governors. How many types of governor are there? It maintains the speed of your lawn mower or outdoor power products. A carburetor that's incorrectly adjusted is a common cause of poor engine idling that results in hunting and surging. Fortunately, most lawnmowers have two screws that allow you to adjust the carburetor yourself. Then slowly adjust the screws tighter or looser in turn until the mower runs and idles smoothly.
To control engine speed, a mechanical governor uses gears and flyweights inside the crankcase to detect changes in the load and adjusts the throttle accordingly. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly. What is the working principle of governor? A centrifugal governor is a specific type of governor with a feedback system that controls the speed of an engine by regulating the flow of fuel or working fluid, so as to maintain a near-constant speed.
