I believe the correct orientation to determine crankshaft rotation is to be at the rear of the engine looking forward. At least this is what I was taught at A&P school and is the same in technical manuals.
That being said, to be technically correct the normal crank rotation of our little engines is clockwise. And you wish to find a way to make it run counter-clockwise.

But these are not full scale engines. That is a different field entirely. Modeling has its own customs and modelers judge the rotation of an engine from the front, which means that our engines run counter clockwise by tradition and all that is holy.
I'm picking on you Kmot. I used to tease Henry Haffke in this way many years ago. He was and is more of a modeler than I will ever be in this life time.
