"Try changing your plug."
Did already, new #8 OS ran exactly the same as the old plug.
I did some more fiddling, found that the uniflow setup created air bubbles in the fuel line. Swapping back to the standard setup got rid of the bubbles, and helped some in runability, but its still poor with nose up and strong with nose level. The great idle is back as well.
I'm starting to think I should just sell the whole damn thing.
