Gil, fine machine!

What's the phasing on the engine?

I'd be very interested in seeing the difference between air vs steam.

 
What I noticed when running my make shift Märklin compound: When 180 phase I don't think running on air  impact performance badly* even though under steam the subsequent expansion wouldn't be there. But at 90 degrees,  noticeable impact. My setup has a timing chain but your fine engine is more suitably engineered. ;)

*My air compressor regulator isn't very accurate so it wasn't exactly the same pressure.
