79 Ford van carb flooding

Hi: I have a 79 Ford van, E 150, 4.9 L 6 cyl with a 1 BBl carter carb: Van cranks, and runs for about 1-2 minutes then carb starts flooding severely, spitting a lot of gas from top. I've replaced the float, etc., but no change. Anyone have any ideas? I recently replaced gas tank(very rusted), and when I rebuilt carb had to clean out a lot of rust sediment in it. Could the fuel pump be pumping TOO much? This vehicle also has a crack in the intake manifold-could that cause the flooding? Thanks in advance for any help.

Replace the intake manifold, get a good used one. It will never run right with a cracked one.

Yes, the fuel pump could be bad. It's cheap enough, pitch it. If there was that much rust out back, it found its way up top too.

Do that, rebuild the carburetor one more time and it should be good to go for a while---check the float specs carefully and always use a new float when you do a rebuild as well as a new choke pulloff and thermostat.

These carburetors, while simple are flooding junkboxes .
