Hi Hawk!There are 3 timing marks,center one is standered setting.Clockwise with the stator advances,counter clockwise retards.Set it on the center mark.You have the stock jetting,does it seem rich?When it signs off whats it do?Blubber,or fall on its face?This may sound basic (youd be amazed how the little things get you)did someone leave a rag in the air box?Start with the simple things and go from there.
