KO, 69-70 carbs are different. The ebay kit has the clip for the needle jet. Supposed to have 120 and 125 main jets but I did not see two in the pic. Also has float bowl screws, yet there are no screws for the float bowl on the carb.:rolleyes
But, I did not see a K0 kit at OBB.

I think the ebay kit is the one I would go with. Some early bikes came w/125's, most came w/120's. I almost snagged them, but I have enuf kits at this time and that would not be a "kosher" thing to do to another HCMF.
