Screws were brittle, every single one of the 8 carbs had seazed screws, with the notches already gone from the PO tinkering.

I made an attempt, but this is too far gone.
2/4 isn't bad, but the 2 that didn't come sure are.

I did attempt heat as well, since the screw heads were gone.
Oh well, nothing I can do now.
No such thing as cheap carburetors, at this point I'm not sure how to proceed, the wire harness is ratty, Ive got no controls, I need to see if this engine can run before I invest any more cash into it.
Fix the wires up to test ignition is all I can think

You can soak the carbs as a unit in straight PineSol for 24 hours.
