If you know where the rod coming up from the governor is, try holding it steady at a high idle and not allowing it to get into the bouncing back and forth. Does it want to stall or still rev up? If it is, then there is a possibility of the float sticking, which would cause an uneven flow of fuel to cause fluxuations in RPMs. But, if it holds at an even high idle, then something is wrong in the area of its low idle be too low and causing the engine's governor to try and recapture a proper operating speed.
