I think I figured it out...after 2 hours of frustration, I finally switched to the 10% I have for my .46 and it purrs like a kitten (I ran 5% before).

That 10% solved all my problems...it transitions smoothly, and idles strong (H.S. needle 1 turn, 2 clicks out from closed; idle screw 1.8 turns out). Is the fuel my answer, or will using it be a Band-Aid over another problem that could occur in the future or a Band-Aid for a bigger problem?
Thanks,
