I know its in my carb, have had to spray some carb cleaner in fuel filter the last 3 times I wanted to go out to a cruise or car show, took carb apart some what today and looks clean, not sure what is the cause for my miss/stumble. as soon as the carb gets cleared out runs great a ton of power!! but man I went to take off from house this am and wouldn't go over 40mph and sounded horrible like a total piece of crap. turned around and replaced fuel filters, have a inline one before the pump, ran better but still off. removed to of carb and looked in and was fairly clean, a little rust color at bottom but fuel was clear not cloudy at all, removed jets and float to clean and wiped all the walls of the bowl and now runs great!! spins tires going into second again!!! but what is the cause of this?? bad gas? a bad carb? or bad gas tank with rust in it? any input will be helpful - o carb was rebuilt about 3 years ago - car does sit for about a month at a time, its a cruiser not my daily driver!! yet my 78 can sit just as long and never have this issue and buy gas at same gas station?!?!?!
thanks
