318 will not start

Have a 73 Coronet with a stock 318 2 barrel. Just got it. The previous owner said car was running fine until about 2 weeks ago and wouldn’t start- just would crank nothing. Seemed to think it was the fuel pump. Have the car home. And it hit and soon as I cranked it. That’s all I can get it to do is hit. Hits better when holding the gas pedal to the floor. I verified I’m getting spark. I changed the ballast and ECU just to be safe. Also it’s getting fuel u can see it in the carb when working the throttle. U can smell gas also and it’s bad out the exhaust after it hits several times.
Is the car just flooded? I tried starting it with the pedal to the floor and never let up and like I said it hits better but that’s it. Any ideas??
