What you would do is turn your flywheel clockwise by hand until you find top dead center. then turn it counterclockwise until your piston backs up 1.5mm or 1.8mm or 2mm or whatever it is that you want. thats where you want your point s to start opening. adjust your stator by loosening the mounting screws and turning the whole stator plate to the appropriate position. this will take a little while to get right. after you find the right spot, tighten down the stator mounting screws. now set your points gap to what you want it to be. I usually set mine at 0.016", but you might wnat it a little bigger or smaller depending on how advanced or retarded your stator position is set at.
