Are you sure the carb is flooding? You mention that it starts and runs for a few seconds, then dies and spits a little fuel out of the carb. Does the carb leak when you just pump up the fuel and make no attempt to start it? Does it continue to leak after it stalls? Maybe you have a stuck reed causing the stalling and fuel spitting back. Please don’t go ripping into the intake manifold on my guess, but I just want you to make sure the carb is actually flooding over.
You mention a new fuel pump, just because it is new doesn’t mean it is any good, perhaps its diaphragm is leaking filling up one crankcase with fuel.
Again, PLEASE don’t rip that fuel pump apart based on my wild guess.
In any event, it might be easier to leave the carb off the manifold with the fuel line connected, then pump up the fuel (while holding the carb in its normal position to confirm that the carb is leaking. This might save a little time and make it easier to pinpoint why the carb is leaking, if it is indeed leaking.
