I changed the distributor on my 400 Ford motor, and it still won't start, and all it does is back fire through the carburator. What could be the cause?

well, if ignition is now working right, then either carb is bad, or you have engine valve problems

Would a bad engine valve problem or a bad carb keep it from starting?
