350 missing and backfire

i have a 350 small block with an edelbrock 1405 carb and a regular points distributor. i finnished it a few months ago and it ran fine but recently it has been acting up. some days its totaly fine but other it will randomly go into a spitting and sputtering fit. it will miss and miss and backfire. its done it a few times so far but after letting it sit for 30 or 40 minutes it was fine. it did it again today but this time it didnt stop for hours. it got even worse and woudl barely run. it sounded like the timing was off but its not ive checked it time and time again and its right on. i also thought the fuel was boiling but i pulled the carb in the middle of one of the fits and the carb and fuel wasnt even warm. im starting to think maybe its and ignition problem. any imput?

Have you check the coil? The coil show problems once it gets hot. Also check the points and condenser, the points maybe burnt. Only other thing I can think of the way you described is the choke on the carburetor.
