Why is your 92 F150 5.0 backfiring through carburetor?
A backfire is caused by many different things. Using the wrong grade fuel will cause a backfire, as the engine's compression ratio is usually too high and will detonate the Air/Fuel mixture, causing a backfire. It can also be caused by advanced or retarded timing. Advanced timing will cause a backfire through the intake, as the spark occurs too early and ignites the Air/Fuel mixture before the intake valve is closed. Retarded timing causes a backfire through the exhaust as the spark occurs after the exhaust valve has opened. Your problem seems to be advanced timing. A backfire is caused by many different things.

Why would A 1995 Plymouth Neon backfire and not want to crank after replacing broken timing belt and lining up timing marks?
You may have lined up the timing marks, but I have had some cars that if you don't have the slack on the correct side of the tensioner pully, when you tighten the belt it causes the camshaft to move about 1 tooth off making it out of time. Check the timing marks again.
