I would try a 155 main, 42 pilot, 2 1/2 turns out and needle on the 3rd clip from the top
i agree on the 155 main jet, but IMHO a 42 pilot is to big. i would go no bigger than a 40 pilot.
40/155k
yeah you might be right about the 42 pilot, I live in Missouri with no choke so it seems that is always my first answer as that is what I run but if you still have a choke the 40 will work for ya
