RJ, my first guess, like others is the firing order, but I beleive somewhere in the past you verified that and even changed the wires around just to be sure. Is that correct?

Next try NEW spark plugs. Certain brands (Champions especially) have somewhat porous porcelin, and even cleaned, will hold enough fuel (or something) in the porcelin to weaken the spark. I really don't know what is happening in or on the plugs, but I've expereinced a bad misfire or no start after flooding a car. Sometimes I've taken a propane torch to the plugs (out of the engine of course) to burn the gas out of the porcelin with good results.

Next in line is one I have said won't happen quickly, but in the past month I've been proven wrong TWICE. That's the cap and rotor. Even ones where there was no visible carbon tracking, or bady erroded contacts, two people who I told that wold not work, replaced them and the cars ran great.

Finally, it still could be bad fuel. Clean or replace the plugs, empty the fuel bowls and pour a bit of fresh gas in them. Disconnect the fuel line between the fuel pump and the fuel tank, so you don't run more bad fuel into the carbs. That'll start it enough to verify if the fuel is good or not.

Good luck!
