One of the most common causes of flooding is trash in the fuel stream getting under the needle/seat. It only takes a microscopic trace to hold it open.
Take a fuel sample from the line in a clean jar, see what you catch. I'm not a fan of inline filters on gravity systems, be sure the sediment bowl screen is in place. Another solution is a short stand pipe inside the tank to keep from drawing fuel off the bottom. But the best solution is a clean, rust free tank.
Back to the carb, I like to do the "suck test" before final assembly. Set the float level, hold the upper assembly upside down, suck on the fitting, hold your tongue over the end of the fitting, see if it will hold vacuum. If it won't, it is leaking somewhere. Be sure the seat is tightening down on the gasket. Look at the needle and seat with a magnifying glass. Any imperfection, nick, cut will cause it to not seat. If the seat is damaged, a Qtip in a drill with valve lapping compound will polish it up. Be sure the float tang is pushing straight down on the needle and not resting on the rim of the seat.
As others said, be sure the float doesn't touch the sides of the bowl.
When I do the final connection of the fuel line, I'll turn on the fuel first to flush the line, then connect it while it's running fuel. That way no trash can get in. Especially if the area is dirty around the connection and difficult to get to.
