I have a 12 HP Briggs engine on a garden tractor. Engine dates back to the mid 90's. The speed control works fine at higher speed but as I slow it down toward normal idle the engine speed begins to surge up and down. Seems like the governor is just not able to hold the speed constant. Its getting to the point now that I have to keep the speed up a ways otherwise it will stall out.
I cleaned the grass and crud out of the governor area where the speed control cable connects and it seemed to help but it didn't last long.
I can run the engine fine at slower speed if I hold the throttle linkage still by hand.
Is this an internal governor problem or ?
