first you have to set your point gap...start with .014".

then static time.....use a test light. connect the aligator clip to the point wire going to the coil on 1/4.......ground the other end. turn the motor clockwise....the light will just begin to flicker and light up.....that is where the F mark should align with the case index mark....do the same with 2/3, then set with a strobe light when it's running.
