thanks johnnyO for the confirmation, I guess I've always lived in the danger zone because I've always set my timing by ear and this has always worked well for me.When the motor is starting easy no kick back no labour knocking under load not running to hot and has that great throttle response then to me thats always been good to go. and right now this motor where the distribitor is setting is hitting it off at the strike of the key move her back just alittle and she is to retarded and won't do right. thanks again.
