I said that the prop is the cause because that is what the MANUFACTURER figured to be the cause (I called the manufacturer after I created this post). They suspected that I put a pusher prop on the engine. Yes, I inadvertently purchased a pusher prop. I put my original prop back on (not a pusher prop), and the engine ran fine.

If this is the case the engine always ran fine.
It never did run backwards like your first post suggests. It ran in the correct directon but pushed air in the wrong directon while doing so.
You had it on the wrong end of the airplane for the prop you used.
You should apologize for wasting our time with this thread.
Do not get pissy with me for your mistake.
