Well, I finally got it after another gallon. I took the engine out yet again and completely disassembled it and cleaned everything. There must have been something lodged in the low speed needle path. And I went back to the Enya #3 plug.

It runs very cool, plenty rich, with this 28% oil fuel it has LOTS of smoke. I can run a half tank through it doing FFF and aerobatics after landing I can put my finger on the cylinder for a good 20 seconds without it feeling hot.

My needles end up at Low (just flush), Hover 1.25 and High .75 turns. Seems rich at these settings but is making good power and it's running cool.
