Had the return-to-service flight today! Was going to be 3 laps in the pattern, and if all looked good, venturing further away for some maneuvers and, you know, enjoying the nice day up here.
Unfortunately, after the 3 laps in the pattern where things looked pretty good, shortly after the 4th takeoff, I noticed what felt like a partial power loss on climbout. This manifested as a very brief reduction in RPM (I don't fully recall, but I don't think there was a reduction in manifold pressure), lasting about a second before returning to normal. Still enough to give me the heebie-jeebies and call it. Re-entered the pattern and landed without any other incident.
I did just have the prop governor overhauled, so it could be that the governor is still breaking in. But I'm obviously going to have a mechanic look at it before I fly next.
