Overall, it sounds rich. You should need some amount of choke/enrichment to get a cold engine to idle reasonably.

The carbs should be synced as soon as you get it to run decent.
Yes, I did adjust the idle mixture screws. I found that the best setting for me was about 2.5 turns out, when below 60 F out. Revving it at that setting wouldn't have any hanging, nor would the RPM go below my idle. The pilot jets are upgraded to a number 40. I have synced the carbs. From another post, I was told that my 117.5 jet is likely too large.

Quick question, how much throttle am I using under no load to get to 6k RPM? It seems a lot of my problems are down low for now. I wouldn't doubt that a smaller jet would help. I have a 112.5, so I'll swap to that and see what happens. What pilot jet would you recommend?

Thanks!
