Dan, By rights, this setup should have diarrea, but works great in my view. There is nothing to slow, reverse, etc. period. If not kept somewhat full, I get slight bit of corn kernels out with straw, otherwise nothing at all. My varieties are picking clean however, if that would make any difference I don't know. The ideal would be to have the thresher side with fast pitch helicals, and sep with regular ones as you have done. That would be my plan for a new machine. How are those machines doingIJ The discharge is the bent back paddle in the outer, lower position.
