If the rebuilder didn't at least make an attempt at sealing the well plugs while the carb was apart, IMO negligence on his/her part. Well known issue for decades. I bought carb rebuild kits in the late 70's that included that little foam pad as a 'fix' for the problem. The pads didn't last long, but even then, the problem was known.

As mentioned, evaporation is your enemy for long term sitting. The bowls on these carbs, either Q-jets or Eddys, are basically open vent to the atmosphere. The gas will disappear after a few days due to simple evaporation. Another place it can go is back out the gas inlet and down to the fuel pump.

More then a few days of sitting, especially if it was parked hot, will empty the bowl even with no leaks. If you still some gas in there after 6 days, count yourself lucky. Especially Texas in summer.
