my kx has started hunting realy badly on the overrun especialy down hills and on a closed throttle . I took the carb apart and the bottom corner of the slide has broken off and been swallowed up by the engine , its a piece about 1/4" square so i'm guessing that that is my problem . Does anyone have any spares that may help me or know where I can get reasonably priced spares , a slide or a carb - its a pwk39 from an 87/88 (i think) . Please help !
