Have you tried turning the gas off yet?

Sorry to keep pressing the point, but I've re-read a few times and see no mention of you trying it.

(although with my A.D.D I often miss details people type, sorry if that's true here)

Just shut the gas off and keep it off. Keep cranking on and off for a good 5 minutes. While the gas gets used up, you'll eventually pass a point where the mixture is just right and it should at least fire a few times.

If nothing - drain what's left in the bowl - pull and clean the plugs.

Try starting it with everything dry using starter fluid only - no gas.

(I think you said you did this without the carb in place, but that might be a little too wide open -- and definitely use starter fluid, or carb cleaner if you don't have the fluid. Spraying gas alone probably isn't enough)

If it goes with the starting fluid, you can be fairly certain it's a carb issue.

If not it's probably a timing/spark issue.

If, like you said, you're getting a 1/4" blue spark, that's good, so most likely a timing issue.

A timing light should show any problems, even while just cranking the engine.

If you don't have a tdc mark on the crank pulley, just put one there yourself.
