Anyone have an engine running smooth for the first 50 hours then develop a significant vibration at moderate speeds only (from around 2000 to 3000 rpm). It happened right after a wot pass I made going full speed at 6000 rpm. Replacing the prop didn't help and the dealer did a diagnostic check on the ignition system which also checked out. I think I bent a valve or something else mechanically is out of balance. Any input is appreciated.
