i inherited my grandfathers 1966 chevy c10 it has the 250 ci Inline 6. the truck had been seating at there has for 2 to 3 years befor i got it. i was surprised that it stated the first time i tryed. Now the problem is as soon as i put new gas in it the truck once warm would sputter and cut out but if you woud let it set for a few min it would be fine. i rebuilt the single barrel carb thinking it was gummed up but the troblem still happens. im lost.
