Do you mean you are getting a backfire out of the carb, if so sounds like your timing if off for some reason, did you touch anything else while working on the car ?
No I didn't touch anything else and yes it's back firing
Check the timing and make sure all the spark plug wires go to the correct cylinders.
I did that and rechecked I'm lost
Check for vacuum leaks but I think you missed something on the timing. Did you get it 180 degrees off? Try static timing - put the #1 cylinder on TDC compression stroke and then set the distributor so that the rotor points to the #1 spark plug wire. This should get you close enough for the engine to start.
Ok I'm going to redo it again
