Europa-List: Rough Engine

[JEFF ROBERTS <jeff@rmmm.net>]

Hi All,
While taxi testing I have noticed the 912-S running rough or vibration 
at around 2600 to 2900 RPM's. It's very smooth before and after that. 
The carb's have been balanced, but my spinner is off about a 16th of an 
inch. Would that cause this?  Is there anyone else having experienced 
this? Is it normal or should I keep digging?
Thanks,
Jeff
