Plug chops is the other thing. I was running a b6hs in the 50cc, and it ran beautifully. The instructions in the metra said b7hs, and that thing looks like #23 here:
It is bone white, which means too lean, which means I need to up jet. But then I am back to my low throttle 4 stroke issue.... I don't know anymore. Hopefully tomorrow will be sunny and warm and I can blow off the yard work and figure this damn thing out!
