If you post a pic of the valve gear and cylinder you should get the correct answer pretty quick.

Ok, rotate the drivers so the main rod is forward (9 o clock) and set the crank to about 2 0 clock that should get you close.

What I gave him is my set up on the Aster Berkshire which has Baker valve gear, which is what the engine in the picture has. IT WORKS, The figure 12 you is for the other side, if you roll the driver so the main pin is forward, 3 o clock the and the eccentric pin will be at about 10 o clock, with the center of the clock being the center of the axle We are in agreement but describing it two different ways You are looking at it with the Main Pin at BDC or 6 o clock I am describing it with the main pin full forward. as we say "six of one, half a dozen of the other"

Yes, Sorry, I was trying to give a simple position with out a drawing like you were good enough to post. we were after all talking about an electric train, not a functional steam engine, where a few degrees can make a difference !
