Going to need some pertinent informaion. First of all, have no idea what an "elde" carb is. Edelbrock, maybe? And I'm thinking a 92 engine is probably supposed to be computer controlled? I see where you say "no comp". No computer? No compression? Is there a regular HEI distributor with no computer control? If you want answers we need info.

So, you have 4 wide open vacuum lines at the moment?

Make sure you don't have more then 7 psi fuel pressure wise but 6 psi would be the best bet as Edlebrocks don't like to much fuel pressure as that won't affect your idle per say but you said the carb was soaked when you took it off. Make sure you check your idle mixture screws settings as well if they are to lean when you put it into park it can make it stall like that. Also do you have a performance cam in this thing as anything bigger then stock will take more timing in order for it also to run right.

Its obvious your flooding it to death. Is the vacuum advance in use? When the carb is flooding the idle mixture screws don't respond. This can also be caused by the throttle being open so far its pulling from the main boosters instead of the idle circuit. Edelbrock carbs don't like anything over 5 psi fuel pressure, if you don't have a fuel pressure gauge get one otherwise your shooting in the dark. Are you using a mechanical fuel pump or the in tank electric? If the in tank electric is used it has to have a fuel pressure regulator otherwise the fuel pressure will be way too high. First off find out what the fuel pressure is, then once we know what it is you can take the needed steps to fix it. If the fuel pressure isn't the problem then either the needle is stuck open in the seat causing it to flood or the float level is too high. After you get the flooding issue contained we can move on to the timing.
