Just manually turn the engine pulley over till the groove in the large pully is accross from the 2 halves of the engine(12 oclock) Pop off the cap and see where the rotor is pointing. It is either gonna be 1 or three. Assume it is 1 and put the wires in the cap in the firing order. If it starts and runs OK. Your done. If it backfires and runs rough. Move the wires 180.
