My engine ran lovely for the first year or so, but now it does this uneven VROOM-vroom, weird surge thing. It starts fine and runs fairly even until it warms up and then starts this silliness. It seems to do it mostly when idling. It is a Briggs and Stratton engine, and I think I have maintained it pretty well- I think I use good gas, with no ethanol. I run the carb out of gas when I am done mowing. I change the plug at least once a year and the oil as scheduled, and clean it after each use. But I am not a small engine mechanic so I don't know what else to do. Can anyone help?
