A governor does the job for you by detecting changes in the load and adjusting the throttle to compensate. Types of Governor Systems Your small engine contains either a mechanical governor, pneumatic governor or an electronic governor. The main difference between the two three are how they detect speed. How Mechanical Governors Work A mechanical governor uses flyweights to creates 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.
