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.

The butterfly or float inside the carb might be sticking and not able to keep a even flow of gas. Try carb cleaner, if it doesn't help, then probably time to rebuild the carb or buy a new one. Also, check your exhaust port to make sure it isn't blocked with debris.

Sounds like the oil and gas  mix is too lean . The oil and gas you're putting in may not the be one the owners manual recommends. So, read the manual.......and read the trouble -shooting page too. Try priming it, but not too much , before you start it . Might need spark plug and carburetor  work, too. How old is the mower ?
