OK BTW, I'm back to square one with the 1.70R. Turn low speed needle back to manuals recommended 3 turns out. I prime it, it burns out the primer and quits. I guess I will keep opening the low speed until it sustains. It always ran before at 6 turns, but now won't transition at that setting. It keeps dropping cylinders. Be back later.
Checked for crap in fuel delivery passage and the spray bar of carb ?,all carb,intake and plenum "o"-rings have perfect seal ?.
