I am the new owner of '50 mdl G. Friends baby-sitting my airplane until I can pick it up tell me there seems to be unusually high vibration above 2,000 rpm. A possible cause is a repair patch on the spinner, although that seems to be a trivial mass change that close to the center of rotation. We think a repair in this location is not legal. Can the airplane be legally flown w/o the spinner? If so, that may help isolate the vibe source. I plan to have the prop track checked and dynamically balanced. The C-85 installed has a taper shaft. Another question: How difficult is it to R&R the spinner on this engine? Grateful for any help.
