Supplement online does not indicate how many turns out for the air screw. Its a 2002 xpedition 325. Think its a mikuni bst31. Anyone know? [img]i/expressions/face-icon-small-smile.gif[/img]

 

start at 2 turns,see how accepts throttle,if boggs may have to turn out further. THE best way is to have a carb tool to reach under carb,turn out counting turns untill starts to stumble at idle,then in till it stumbles and set in between.Usually between 2-3 turns.
