Backfiring

720. To be sure we're on the same page that's 2 full turns.
Like if you marked the top, it would start at the top, turn 1 full turn back to the top.

Hey Patton.
I've verified everything number and wiring wise.
I finally just bought some sea foam and ran it through.
It's getting better but it hasn't been fixed yet.
Cylinders 1-3 sizzle when sprayed and now 4 will a little.
They're all now too hot to touch. Before I could hold 4 no problem.
I think the not getting fuel post was right. I'm going to clean them.
Again... Lol. Then run more sea foam and hopefully be fixed up.
Thanks again guys!

If you have access to an air compressor, or even compressed air in a can, spray carb cleaner thru the passageways of the carbs, watching where the liquid exists... and follow this with compressed air. We're talking about small passageways that are easily clogged/blocked. You'll be able to see if there are any restrictions to the spray cleaner.

Points and timing - after the carbs are clean (take them ALL apart, and clean/inspect piece by piece. dumping anything into the gas tank is only a temporary fix).
