Anyone jet a 24mm nibbi on a predator 212 or Tillotson 212r?

Hey hows, it going my first post I tried doing a search but kept coming up empty. I got my jetting set to the point there is zero bog when you snap the throttle but the plug still looks sooty as heck. It started out as a Tillotson 212r so 196r head 26lb springs, billet rod, .265 cam. and the nibbi carb. Current jetting is a 50 pilot and a 130 main. It eat's it but figured I'm still running rich and maybe one of you guys could point me in the right direction thanks in advance.

Got pics of your plug??

Where's your ignition timing set at???

28* BTDC is a good starting point.

All that excess soot and carbon build up will play hell on them rings later down the road.
