A dirty or gummed up carburetor causes an engine to surge. If you feel comfortable working on carburetors, unbolt the bowl and clean it thoroughly. Check whether the float moves up and down without sticking, and clean the tiny ports on the bowl hold-down bolt.
How is governor speed controlled?
The governors are control mechanisms and they work on the principle of feedback control. Their basic function is to control the speed within limits when load on the prime mover changes. They have no control over the change in speed (flywheel determines change in speed i.e. speed control) within the cycle.
How does a speed limiter work?
The limiter is set by the driver: you select the maximum speed that you want to travel at and then drive normally. If the car reaches that speed, then it won't go any faster, even if you continue to press the acclerator gently.
What are the three types of governors?
Typically there are three types of governor fitted to modern diesel engines. Mechanical, Electronic and Electronic Control Units (ECU). Each type of governor has its advantages and disadvantages which makes it suitable for different applications.
How does a mechanical governor work?
How Mechanical Governors Work. A mechanical governor uses flyweights to create a force based off of crankshaft speed which is balanced by the force of the governor spring. The top engine speed is varied by increasing the spring force to run faster or decreasing the force to run slower.
What is a governor in a small engine?
Your small engine contains either a mechanical governor, pneumatic governor or an electronic governor. The main difference between the three are how they detect speed.

The pick up tells the controller how fast the engine is running and the controller tells the stepper motor to open the throttle more or less to keep the desired speed .
Why does the governor blade pull the throttle plate toward the closed position?
Air blown by the flywheel also begins to increase, causing the governor blade to pull the throttle plate toward the closed position in its effort to maintain a steady engine speed. The pneumatic governor design is simpler and parts are easier to access.

What happens when the crankshaft spins?
When the crankshaft spins quickly, the flyweights open up, putting pressure on the governor cup and crank. This closes the throttle, limiting the air-fuel released into the engine. When the engine load increases, the crankshaft spins more slowly. This leads the flyweights to relax and the throttle to open back up.
What is a lawn mower governor?
