A kid friend of mine screwed w/ his carb, doesn't know what he did, and lost his manual. Anyone have an idea on the fuel screw setting? Anything else on that carb he could have messed with (external adjustments other than idle screw)? ------------------ 99 WZ, all YZ mods, de-octopused, OEM YZ tank and IMS seat, jetting by Clark/James, got forked by Pro Action, DSP airbox, PB Header, Stroker SX-1 SA, Thumper Rad Guards, Acerbis Hand Guards.
