My bronco will not start after changing from a fuel injected intake to a carcarborated intake???

I have an 86 ford bronco, I changed it from electronic fuel injected to a carborator. I have done everything I can possibly think of, it is now spitting gas and fire from the top of the carborater. its acting like it wants to start, but it just won't. I checked to make sure it even has fire, it does. I've moved the distributor cap all possible ways. I have pretty much done every single thing I can think of and what others have told me to do. Help me pleaseeeeeeee!!!!
