The governor is in place on small engines so the flywheel doesn't spin too fast; therefore it restricts the RPM. When you want to increase the power and speed of your five-horsepower Briggs & Stratton engine, you will need to remove the speed restricting governor located next to the flywheel. When the flywheel spins too fast, the plastic flap of the governor flies out of the flywheel and pulls the engine's throttle down via a spring attached to the throttle linkage.

  1. 1

    Remove the metal flywheel shroud from the top of your five-horsepower Briggs & Stratton engine. There are six bolts holding the shroud to the engine block. Unscrew them with the appropriate-sized wrench.

  2. 2

    Pull the shroud off to expose the flywheel. Locate the white plastic governor flap bolted next to the flywheel.

  3. 3

    Unscrew the bolt that holds the governor onto the engine block, using a 3/8-inch wrench.

  4. 4

    Unhook the spring running from the governor to the throttle linkage eyelet.

  5. 5

    Replace the engine shroud and tighten it back on.

Tips and warnings

  • Removing the governor from your Briggs & Stratton engine will void the warranty on the engine. Without the governor, the engine can run at high speeds so be aware of this and adjust your throttle accordingly as you run the engine.
