sorry - this photo has been posted before. It usually stops the thread cold.

Nice model, but the eccentric crank is set for an inside-admission cylinder (can't tell if the connection between the radius rod and combination lever is correct). For an outside-admission valve, the eccentric crankpin should lead the main crankpin; here it is set up to follow it.

Don't know why it was designed that way, but with the inside cylinder inside admission, they could have designed direct porting from the inside cylinder exhaust to the outer cylinders intake.

Not a bad looking engine, though. Who built the model?
