hey guys got a question. ive had my engine out and just got it back together and put it in, went to start it and had no spark. never had that problem until today. have had the engine out many times. any help or suggestions would be greatly apprieciated. im not sure if i went brain dead and missed something but i checked it all out and found nothing wrong. parked it and it ran only on two cylinders but it did run. thanks brian
