Default Ys 63 FZs

Hi Troy,
Ys 63 FZs ,
CP 30 %
APC 13*6
Climate: very comfortable 20C, low humidity

This morning at the field my engine seemed to have lost some of it's power especially around mid throttle ( it returned from service approx. 2 moths ago with a change of ring, gaskets and a rear bearing ).
Transition, and idle are perfect. After landings the engine was warm to touch ( could hold my hand on it for a long time ) The engine also seems to smoke quite a bit without leaving oil residue on the plane. Any ideas?

Thanks in advance,

Might just be too rich.

If it was overheating and loosing power it would be very hot after landing. The cooler temps will afect the needle settings. So repeak the engine and back it off the 200-300rpm from peak.

I flew in contest in California this past weekend and I had to adjust my HS need Richer by over 1/2 turn. I went lower in elevation and 20degs F cooler.
