I'm guessing rich on low. Check out the low needle tuning in fist post and try that. Also make sure the little idle set screw in the carb is removed.
@jhelber08 sounds like an ignition or possible IBEC as well. What type of IBEC do you have? If you have one, I would try an ignition swap first though.
Techaero Ibec. I do have a spare twin da ignition and that is the first thing I plan to try when I get back from offshore...just didn't have time to do it as it was the morning I was leaving for work I also have a few brand new Ibecs as well since I was planning to convert all my planes over at some point.
