Governing: While some people think that a governor on an engine is to prevent overspeeding, (that was me, guilty as charged) the real purpose in the small engine field is to maintain a desired speed regardless of load. With a fixed throttle position, the engine could speed up if the load was lightened; if the load is increased the engine would slow down or even stop. (this is a quote from a Briggs and Stratton repair manual)
This video DOES NOT demonstrate the procedure to set the correct FIXED THROTTLE POSITION of the carburetor. It DOES demonstrate how to position the governor arm to a carburetor that is already in the correct FIXED THROTTLE POSITION.
This particular engine will be mounted on a rototiller and will be placed under load on a regular basis. A governor is necessary and should not be removed.
