Oops, it was NM2K, not Broken Wings  that suggested sticking with "Nearly stock size", sorry for the mix up there.  NM2K, you mentioned the 8mm carb size, so you think that would be a good step up from the stock size of 6.8mm.  or just stick with the Completely stock size?  they have them both, 6.8mm and 8.0mm.

Thanks, Craig.
