Jim Clark sent us a video of starting up the engine on his Waco ASO:

Jim says: "This morning, April 8, 2009, the boys at Raven Aero on Freeman Field, Junction City, had the 1929 Waco ASO ready to test run. The engine on this aircraft is a Wright 760-8 that came from a Navy N3N. 760 cubic inches started with an inertia hand crank starter. We wanted to start the engine prior to installing an electric starting system. Watch the effort put forth by 2 men to spin this up and you will understand why we are installing an electric starter. 12 minute run up condensed into a 4 minute video posted on photobucket."
