 Mike - As I had stated before, the McCulloch and Yamaha PTO tapers are both 10 degrees, with the Yamaha taper being shorter than the McCulloch taper.
As to Mark's post, I believe that the 9 degree 30 minute angle is what is used on the IAME PTO. I do not have any IAME cranks to measure, but in any case they are different from the Yamaha and McCulloch PTO tapers.
I took from your original post, that you were only trying to verify that the McCulloch and Yamaha angles were the same.
