Carb is about dialed in now. The main jet is still the 147.5 and the needle is shimmed pretty far. The real change was I had to change the 52.5 mid jet, or whatever it's called, to a 70 with the mix screw backed 1.25 out right now. Plug looks good after driving at this setup. Going to invest in a infrared thermometer and get some temp #s to post.
Here's the plug with about 30 miles on it... damn near perfect. I switched to the ngk iridium. The e3 was too cold and even had a more black base ring and insulator indicating I wasn't burning as well.
