A lot depends on whether the car was running normally when it started its long down time in which case it should be pretty easy to get going again,  or had some problem that made it a non-runner and was then left.  In that case it could be anything, and if someone has been trying to fix it and failed then there could now be any number of things wrong with it.

Cranking for a while with the choke out should result in a strong fuel smell if fuel is getting through, and the plugs should be soaked.  If they are dry there is no fuel getting through.  Float valves could be gummed up.  

Year?  Carbs?  If HSs give the top of the float chamber a sharp rap with the plastic or wood handle of a large screwdriver, or similar.  But if HSs then it's easy enough to remove the lids and look inside.  HIFs are a real pain as the 'lid' is on the bottom so it's a real fiddle to get them off unless you remove the carbs, and you should replace the O-ring seal.  The Zenith looks much the same, so try rapping the lower body in those cases.  In either case the symptom of stuck float valves would be little or no chattering of the fuel pump when you first turned on the ignition, with empty twin carbs this would normally go on for a few seconds.

HSs could have the float bowls full, but the jet pipes blocked with muck, or the seal where the pipe screws in to the float bowl decomposed.  With the air cleaners off check you can lift the carb pistons, and that the needles come out of the jets.

As for old fuel it depends where you live.  If you have land burn it, if you live in a neighbourhood with a waste oil disposal facility nearby then they may take it.

  Two things in question:

  1)      How do you dispose of drained gas from the tank?

  2)      Initial suggestions for determining fault in restarting my A after draining and refilling tank and a long down time?
