Pulled aircraft from hangar and chocked it in position so prop blast would not interfere with hangars or other aircraft. Positioned truck behind aircraft and chained tail tie-down to truck hitch. With assistance from Brad Ransom, Larry Diebel, and Jim Jones (Judith Kelley video recording), I performed the initial startup. The engine ran well but there was no RPM indication from the engine monitor. I ran the engine to full power by guess and exercised the prop, which worked properly. After almost 5 minutes of uncowled running, I was signaled to shut down. The safety crew had noticed an oil leak, apparently from the base of the oil filler tube. No other problems noted.
