Those plugs are shot. throw in a new set & see if it straightens out. Is that wet oil or dry carbon?
it was a mix of each. they cleaned up okay so i reused them. im going to put new ones in once i get my first check

I'm probably going to get flamed for this, but, IMHO, get rid of the Champions. I've run Autolite copper plugs in my MOPARS since my first one, back in 1969. No issues with them, ever.
For your application, plug number 85. $1.60 at your friendly Autozone.

 I've used 85s for over 25 yrs, but that carb looks to be fouling the plugs..fix that first. May be float level or rich idle mixture.

plugs look badly oil fouled, take a close look at intake manifold sealing. You could take the carb off and you may be able to detect oil in the plenum.
