There is a product out there called Startron Enzyme fuel treatment---we buy it at Walmart---takes the alcohol out of the gas---we use it in everything---mowers --trimmers-- jet skis--motorcycles-etc---was told to use it in our Harley at first and now we use it in every thing that runs on gas---trust me this really works---we also try and buy the lowest ethanol fuel possible---we buy it by the case
