It's common for the well plugs to leak and drain the float bowl.

It will need a rebuild. Most of the kits include a "sponge" for this purpose, but I like to seal them with epoxy.

And don't forget to replace the float too.

I would agree it's probably leaky well plugs.
This can cause problems. If they're leaking badly the fuel can run down the intake and eventually end up in the cylinders were it seeps past the rings into the crankcase. I personally witnessed a guy almost blow the valve covers right off the engine of his chevy truck because the fumes in the crankcase ignited. As soon as I saw the q-jet I figured out what happened. We both nearly crapped our pants that day.

I agree with the others the well plugs are most likly the problem. I have overhauled lots of Q-jets working for GM dealers over the years. The best stuff I have found to seal them is Kent 2 part epoxy. One tube is clear and the other white.

The gas in the carb does evaporate over time because of the bowl vent. Not much you can do about it. Try giving the pedal two full pumps before you try to start it and then crank it with your foot off the pedal. This will allow the choke to close all the way. If the choke and fast idle are set up right it should fire up quickly. If it doesn't start after 5-10 seconds of cranking repeat the above procedure.
