what could be the possible cause on a 350 chev engine after sitting over night the car will not start, it cranks and cranks and i can pump the heck out of it to no avail, i need to pour a small amount of fuel down the carb, than it will start and run just fine. if it sits a few hours it will start fine on its own. has to be like 8 or more hours.
thanks Harlan
