My engine started to run rough on climb out, cleared up, and ran rough again.  All the inflight temps and flows were completely in line with previous flights.
Ran a new conditional and found nothing amiss.  Compressions good, plugs clean, oil filter had no metallic.  Ferried it to Kelly Aerospace for work on the A/C and de-ice (mice in the wing!) and the 45 minute flight was uneventful.
However when Kelly flight tested the plane it seemed sluggish and it ran rough again.

Thinking about a tear down and inspection but not expecting a complete rebuild.  Anyone recommended who could be within 1 hr or so of central Ohio?
