Trying to figure out what's normal and what's a problem in my RV10.
After cleaning injector nozzles at the advice of someone to help find a different problem (an EGT dropping with reduced power), I made flight #3 this morning and noticed a pretty bad vibration that was not there on flight #1 or #2. I could feel it in the floor through my feet and in the stick. High frequency - like I was holding a small electric detail sander. Had to let go of the stick a few times just to get a rest from it. Was planning to fly two hours, but called it after only about 40 minutes partially because of this vibration and partially because of rain.
I was running 2300, 23"-26" (varying between 65% and 75% power). Vibration much worse at 75% power, still there but much diminished at 65%. Not there at all when I reduced power to descend and land.
Standard Van's FWF:
IO540-D4A5, 2 blade Hartzel CS prop, dual mags.
Any comments or ideas?
