How does a Briggs and Stratton governor work?
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.
