85 454 Ltd won’t start

I just bought the bike it was running but spitting fuel out the carb so I took it apart and cleaned it put it back together and now it’s not sucking fuel to the motor it’s getting gas to the bowls of the carbs but won’t pull it out if I put my hand over the carbs it will pull it out and run for a few seconds
