Most likely the choke operation is the problem, It should be completely closed with slight tension on it when completely cold. If not, you'll be pumping the accelerator 10 times to get it to start cold and constantly feathering the gas to keep it running for the first few minutes.

Another problem could be the bowl plugs leaking and emptying the fuel bowl overnight, and having nothing in the fuel bowl upon start up would also necessitate getting fuel/ether into the intake tract. Q Jets are notorious for this problem and removing the carb soon after driving and keeping it level and upright will allow you to lift it up overhead to see if in fact the bowl plugs are leaking fuel. The odd shaped hole between the primaries is where you'll see fuel seeping. If the problem is after a few days of sitting the deathanol laced fuel will evaporate also leaving the float bowl empty.
