i let is sit out over the winter cause i didn't have a place to store it. anyways, it idles real low and has alot of hesitation to it. I'm thinking of taking all the gas out of the tank and replacing it. But what i was wondering is there a good gas treatment that i can add to the fuel tank to kind of clear out the carbs and get rid of the hesitation. or is there something else i can do becuase i don't have alot of money at this time. any help would be appriecated.
