Ok. Bought my prowler new a yr ago this month. Filled it up with gas then. Have only put 58 miles on it. Ran fine last fall and through the winter. I went to take the snow plow off yesterday and check everything over and take it for a quick run down the road. When I would get on the gas it would bog out around 25-30 mph. Would bad gas cause this? It idles fine just kinda bogs out almost like a carb machine would if the carb was gummed up. This is a 550 efi prowler. Just wondering what your thought might be on this. Thanks for any input you might have.
