Hi Jerry,
 
Can you post a picture that shows an example or two of an "adjustable strut".  As pictured, it looks like there would still be quite a bit of weight on the rear of the engine, so the strut can't just be a trivial piece.  Goodness knows that if this evolved on the other list, it's been engineered way beyond my tolerance, but I just can't quite picture what you have in mind for the rear support. 
 
Doesn't Atkins also use a beam system like this?  I seem to recall that he used to sell the beams, but you were on your own to make the mount.  Could be wrong about that.

Rusty, I took the attached photo of my engine today. Unfortunately the engine is not on the airplane but on a stand and the strut is not hooked up. The engine is temporarily supported by a piece of square tubing slipped under the pan. I think you can get the idea of how the strut works however. If we can get Bill Schertz to send a photo of his strut you would see a completely different way of doing it.

The strut has rubber cushioned rod ends, left and right hand threaded and acts like a turn buckle. The engine's pitch can be fine tuned by rotating the strut.

The idea was pioneered by Questair so we are going into unfamiliar territory. Jerry
