Well, This thread still isn't solved. After replacing the float needles and seats, setting float height to 7mm using the method outlined in st-riders and idling for 5 mins with new spark plugs I was greeted with Cyl. 3 still being black, Cyl. 1 being dark brown, and Cyl. 4 and 2 being nigh clean still with some touches of brown appearing. No Choke was applied, the idle was adjusted at 1200 cold for testing purposes. I have same colored spark (I will be buying a spark plug tester later today), there were no holes in the diaphragm for the carb slide (although was a bit sticky.) Last time I checked the air cutoff valves were fine, but will probably be checked again.
Soo
1. Either my coil is bad, not bad enough to drop a cylinder but enough to miss and soot a plug..
2. Some how, excess fuel is getting past the new needles and seats despite having appropriate flow on the pump, the slow jets at 40# and the screw turns at 1 7/8 for each cylinder, compression at 165 all around each cyl. I noticed raw fuel on Cyl. Number 3 plug where the others did not have, and Cyl. Number 1 was heading the way of its brother. Sync is good, none of the throttle plates look out of whack compared to the others... Air cut off looks good.
3. At higher RPMS and idle, a translucent cloud of white smoke can be seen puffing on every occasional miss at idle.
I'm at a loss. I'll be shotgunning some parts here real soon.
