Need help getting my car fixed!!!!!

So i will start off saying im not a mechanic but i need someone to help me get my car running. Im done messing with it i have done everying people have told me to do but it will not run. I have a 63 plymouth valiant it was running when i first got the car. I had my dad replace the points and condenser it was dark outside anyways a screw from one of them fell into the distributor and i turned the car over and well it sheared part of the plastic gear on the distributor off. The cam still moved and now its all out of whack. I bought a new distributor and have done what everyone has told me to do but it will not run. Its backfiring through the carb. I need someone in person to please help me im tired of messing with this thing.thanks
