I guess I don't how that could have happened. I verified my rotor on my dizzy was running clockwise before I attempted to start the car. I'm really puzzled as to why the pushrod broke. They were supposedley hardened but I replaced all of them with ones I know were heat treated (from crane). Anyway I got it back together today but I'm afraid to start it again. Maybe I was trying to start it with to much advance 19 degrees.
