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.Click to see full answer. In this manner, how do you adjust the governor on a lawn mower?To adjust the governor, you would loosen the screw on the bottom of the governor arm and push the governor arm so the throttle is wide open. Then you would turn the bottom “clip” (which is connected to the governor shaft) counter clockwise. This will set the governor shaft on top of the governor spool.Beside above, how do you adjust the governor on a Briggs and Stratton engine? First, loosen the arm until it is moving freely. Next, open the throttle to full capacity while making a note of which direction the arm moves in when the throttle moves through it. Once the throttle is fully opened, move the governor shaft in the same direction the governor arm traveled. Also to know is, what does a governor do engine? Governor (device) A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine.How does a governor work on a Briggs and Stratton engine?It maintains the speed of your lawn mower or outdoor power products. When Briggs & Stratton governors are adjusted properly, they keep your speed steady regardless of engine load (the amount of work the engine must perform). When powering a lawn mower, engine load can be affected by hills or height of grass.
