stork955 Posted February 14, 2009 Report Share Posted February 14, 2009 Gday, basic rule rule for mixture screws is - if it is on the inlet manifold end of the carb, screw in for leaner (usually around 2.5 turns out from seated). If it is on the aircleaner side of the carb screw out for leaner (usually around 1.5 turns from seated fully). Check the aircleaner is not dirty or over-oiled before you play with it. HTH Cheers, Stork Quote Link to comment Share on other sites More sharing options...
