Rev Limiter

What does the rev limiter look like on a Briggs and Stratton vertical shaft engine? Is it possible to remove it and what would it do to the engine if it was taken off?

On the outside of the engine you should see a little arm and some linkages connecting it to the throttle butterfly on the carb. If the engine goes too fast, the lever moves and closes the throttle.

Without the rev. limiter the engine has no limit to how fast it can turn. Most engines are happy with a top end of 3'400 to 3'600 rpm. When over reving the connecting rod or oil splasher seem to be the first things to go. If the connecting rod breaks it punches a hole in the side of the engine case. If the oil dipper/splasher breaks other major engine problems are not far behind. It's pretty hard to blow an engine when it's under any load but is rather easy to do when playing with it on the bench when there is nothing connected to the output shaft.
