Bob, A couple of weekd ago Richard Durgee sent me a picture of a Gray "U" which might be of help for you. It is too large to post here so I will email it to you. It doesn't show the inside of the engine but it shows both side views rather nicely. There is also a good picture of the Gray "U" in cutaway picture in a publicaion call ONE-LUNGERS and Other Early Marine Engines which might also help. It is on EBay as a buy it now for $7.50, Item # 120542791996. Frank

If the timer rotates 360 I would set it straight forward, piston at to dead center, contacts closed so the engine will fire in this position.
