I'm not flaming you here, but I say this quite often and the same thing applies to you and everybody else that is guilty of the same crime.
You cannot time it "by ear" It's the same thing as shooting in the dark. Get a timing light and find out where the timing is otherwise your wasting your time and your asking for parks breakage when detonation sets in and ruins your engine. Once you get the timing where it should be if it still won't idle it will need a stall converter.
When you get a timing light, with vacuum advance disconnected and plugged, set it to 12 degrees before top dead center. Lock down distributor. Now plug in vacuum advance to a full time manifold vacuum source. This is a source that pulls vacuum at idle. When you connect it right away it's going to idle up. If it does not the vacuum canister is ruptured. Now recheck the timing. It should be 18 to 24 degrees before top dead center. Now idle it down to 700 to 650 RPM and reset the idle mixture screws. Now put it in gear and see if it idles, if not then more than likely it needs a stall converter.
