I notticed the LH thread, PTO side too. I had three ideas. First, cut it off and rethread: the shaft is pretty long. Second, make a left and thread tap: that is a pain. Finally, an ungainly hub that used the LH nut and a second piece that bolts over the whole works with several cap screws. I will be ditching the Flywheel.

Hey, that jug has so many fins that it looks like an angry porkypine. Anything wrong with removing the fins below the intake and exhaust holes? Make it more like a DLE-30. How about removing all or most of the belts of aluminum around the case? I think I could pare it down a bit more.
