I am guessing motor was 180* off.


I found a friends tractor to be 180 off. Ran fine but hell to line up timing marks. I switched it back.

I pull valve covers and see if valve are open or closed on number one cylinder at TDC?


You should be able to use compression of cylinder to determine if TDC then see where timing marks are.
