Small Engines (Lawn Mowers, etc.): engine governor, engine governor, small engines

Question
I have a BS model 253707 type 0247 01 code 87010910  Can you give me a detailed description to reset engine governor.  I was told there is a nut to loosen and rotate pin which is located under throttle and choke housing. Engine runs at full speed at any throttle setting.

B&S engines have a spring in the governor arrangement. You want to change tension on the spring to change the speed. (This is basically true of most other small engines as well but the details will differ.) The spring is attached to a metal tung (strip) in the linkage at front of motor, this is made of a tinny metal so you can easy bend this tung. To lower speed you want to lessen the tension on the spring. You can do this while the motor is running at top speed but it would be safer to do the bending while mower is not running. By pushing in tung you will lessen top speed gently as it doesn't take much to alter that speed. Often this tung gets knocked in while mowing around bushes or other protruding material and "hey presto" your engine is only idling. It is a design problem that briggs should be working on,
