Glad you were able to straighten that spider arm, but the crank sounds a bit sketchy to me. Is it alloy or carbon sandwich?
The "buzzing" as you called it can be reproduced with any new CenterTrack install that is more than a couple millimeters out of alignment between the front & rear timing rings, or as in your case with a bent spider arm.
