Droop is the decrease in speed that occurs when the governor output shaft moves from the minimum to the maximum fuel position in response to a load increase, expressed as a percentage of rated speed. If instead of a decrease in speed, an increase takes place, the governor shows a negative droop.
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.
The governor itself uses a rotating mass applied against a spring to adjust the carburetor throttle shaft and to regulate the engine speed around a set point established by the throttle lever position. Consequently, the first step in governor inspection is checking for any signs of malfunction.
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.
A governor does the job for you by detecting changes in the load and adjusting the throttle to compensate. Your small engine contains either a mechanical governor, a pneumatic governor, or an electronic governor. The main difference between the three is how they detect speed.
