hi, i need help with 1980 bat m-48, encarwi -25 mph carb.-idle adjustment screw wont slow down the rear wheel from spinninng to fast.
before my complete overhaul: new points/cond.i cleaned the carb. with it off the engine, i rmember turning the screw out this means the throtle valve was not inside. when i put the carb back together was the throttle valve supposed to go into place like it did or was the idle screw suppossed to be comletly turned in clockwise before installing the throttle valve? does this idle screw controll the amount off air intake only or does it work in conjunction with the throttle valve greatful to all who comment. -tim
