That reminds me, my plane developed a vibration 20? hours after first flight.  It was airspeed dependent and sounded engine-like.   Turned out to be the cowl rubbing on the left intake manifold.   It was airspeed dependent because pressure inside the cowl tended to force it into more of a sphere, pulling it closer to the manifold.
