anyone have any luck with it? i tried it on a back up new clone carb and no matter how far i back it out it is still lean. :censure: as far as mods ported milled 3angle valve job valves back cut, rlv pipe air cleaner 1.3 rockers billet rod 26lb springs 5w30 castrol gtx for oil. now with the old carb and 90jet it runns way better just a bit lean for the new setup :doah:
