Thanks Norm, I might be better off sticking to the A33 because even when I had it running on the very wide angle with the G400 engine they lasted for years.

Thanks for the extra info Max. I guess what I was suggesting is that the original engineering had the motor crankshaft on about an 8 degree angle to the big wheel pulley, so I guess I should trust the "tried and true" and keep the new engine aligned in the same way.
