Difference in Cox engine speed between pusher and tractor?

I was just wondering if there was an appreciable difference in the Cox engines when run as a pusher vs. a tractor configuration. Are the ports somehow timed to run better in the normal clockwise direction?

No...they are not, rotation direction makes No difference whatsoever.
Possibly varying friction on thrust plate vs Crank face might... if any.

The reedy run either way the same, Cox TD requires pusher prop or KK crankshaft!

Okay, thanks. The reason I asked was because I wanted to use a couple of the Cox Sopwith Camel propellers on a couple of vintage design airplanes, and the props are left handed props.

+1

If you're using the engine in a standard tractor configuration with a left-hand prop, you'll see no difference on the reedies.

Difference will be in the props used. I don't think the pusher props are as good as many of the tractor props are.
