Checked the valve adjustment to a nominal .007" (.006-008 spec).
Removed the plugs for inspection and reinstalled them.
Did an additional compression check after the recent ground runs and the cylinders were within ~1psi of each other.
I had the prop set at the maximum of #5 pitch (0-5 available) and got about 2500 rpm at wide open throttle. I checked with Sonex and they suggested using the #1 size pin to get the desired 3000 static rpm. I re-pitched the prop to the #1 pin setting.
Received the MASS DOT registration today. Applied the 2014 sticker near the aircraft data plate.
