RE: RCGF Engines
It can get a bit messy if you are not carful but you can reset your hall switch to see if that helps. I put it right back where you had so it could be retarded a few more degrees. I have found with the RC Xel CDIs that are used in these engines seams to like about 35 degrees BTDC. If your low to high transition is good that might not be a factor.
