Specifically for -3's, but all comments about eliminating vibration are welcome.
Patient: 1996 RV-3, 0-235, Sterba cruise prop 66 X 68, Brand new Slicks, harnesses, fine wire plugs, new carb, comps are low 70's, dynamically balanced 6/08.
Diagnosis: The vibration is under full power only, stops when throttle is pulled back. I have switched F&R mags in flight on & off with no difference in vibration. It just seems to be more than there should be, but not enough to ground the plane.
Treatment: I found a few areas where the cowling was touching the air box and I modified it to clear, but I just found it is still touching a little. The spinner may be touching under load as there are some marks on it, but not enough to worry about?
Is the -3 just prone to more vibration that other RV's?
Any comments greatly appreciated.
