Collie Posted June 24, 2006 Share Posted June 24, 2006 try leaning off air fuel the mixture by turning the screw on your carb,not the idle screw the other one. just do it a 1/4 turn at a time . then run it for a day to assess if its any better . remember to make a note of where you started from, Link to comment Share on other sites More sharing options...
