Reminds me of two guys I found working on an old gasser, in a trailer, with the flaps down, cause it was cold. Lips were blue, and they could hardly talk. Not good for your future.

My set seems to be going 2x or 3x the speed of yours with or without a misfire. So frusterating i don't understand how my pumps can be overfueling like they are.I would remove the cast iron exhaust manifold and inspect the smoke color and air temperature of each cylinder.
Here is an 802 I had recently worked on. The cylinder nearest the radiator was not getting fuel. Exhaust color was different, and the air coming out was cold.

You will get there.
Did you test them by attaching the fuel lines with them positioned off to the side?
I doubt the soot is the root cause, but rather the effect of the real problem.
I'd check to see if you have a deeper mechanical problem with the injectors before cleaning off the soot and reinstall.
Or better yet, clean them, then test before installing, just to try to verify root cause.
You can disassemble and clean the pintles and the 4 holes in the nozzles.
You should be getting short 4 radial spray bursts out of the sides of the tips.
any dripping, squirting , fuel stream etc. indicates a bad injector.

Skip to like 40 secs. in Slo mo camrea is amazing..
So the injecotrs were not shooting like that right off the bat,, i had to clean them... Maybe this whole problem became because i didnt have them tight enough and they leaked and i lost compression..???
I had to crank over like 5 times before they did that tho,, and for some reason cylinder one happens to be not playing its part and unfortunately i cant test all 4 at once because of the way the lines have the bends.. how is that spray pattern??
While I suspect something is off on your governor or rack, or possibly timing, I do wonder if it would be worth your while to clean your fuel lines downstream of the final filter. Cylinder 1 not firing either means the injector just plugged, or the pump isn't coming up to pressure. Since the pump and injector were functioning for the first video, I'm inclined to think that the injector got some debris in it.the three mocked up injectors look great, now cyclinder one injecion pump has no fuel coming from it.. (wack a mole with these fuel issues)
