My petrol flymo has run grest all year, then recently the engine started to rev up and down as if it was getting starved of fuel or somthing? Can someone help me? It has a briggs and stratton engine.

sounds like you have water in your gasoline or the bowl unscrew the tiny screw pin on the side where the gas flows into and let the gas run out awhile. If you let it set all winter without draining the tank water can settle in the gas tank try draining the gas tank.
