1939 Daimler V4½ walkaround

After a little tuning, I got the engine to run fairly smooth. 750 RPM, about 40-45 psi oil pressure, and running @ 10 degrees initial advance. It's way to rich on the transition circuit or the mains are coming in too early so there is a stumble off idle, but it will clear out if throttled past it. Revs pretty quick for a 4.5" stroke and that massive flywheel.
