Erratic Motors Motors that drive machinery with fluctuating power needs are the largest culprit in the search for the cause of surging. Less Likely Reasons Clogged Carburetor: A clogged carburetor is most often due to leaving fuel in the generator for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance than can flow through the fuel system effectively. This sticky fuel can clog up the carburetor and cause the engine to stall or run rough.
