All Tecumseh engines come with a rated RPM -- revolutions per minute -- marked on the information plate on the engine's flywheel shroud. This is the RPM controlled by the governor on the engine. Any higher RPM might cause the parts to wear faster, according to the manufacturer. You will void the engine warranty by removing the governor, but by removing the governor, the RPM will increase on your Tecumseh engine.

  1. 1

    Remove the Tecumseh engine cover. There will be six to 10 bolts holding the cover over the flywheel on the engine. The bolts are around the perimeter of the cover and screw into the engine block under the flywheel area. Use the proper-sized sockets to remove them all.

  2. 2

    Pull off the Tecumseh engine cover to display the flywheel.

  3. 3

    Locate the governor bolted next to the flywheel. The governor is a small rectangle-shaped plastic flap bolted next to the flywheel and has a spring running from the end of the flap to the carburettor throttle eyelet.

  4. 4

    Unscrew the bolt holding the governor into the engine block next to the flywheel using the correct socket size. Unhook the spring from the throttle eyelet on the top of the carburettor.

  5. 5

    Set the governor aside, and replace the flywheel cover.

  6. 6

    Tighten the flywheel cover bolts back into place with the socket ratchet.

Tips and warnings

  • Shake the muffler on the Tecumseh engine. Sometimes it can rattle loose and will cause decreased backpressure in the engine, therefore lowering its RPM. Tighten the muffler bolts with the proper-sized socket if they are loose.
