Sometimes a piece of trash gets caught in the needle valve.
The first thing to try, close the fuel valve, open the separator bowl, clean it out, be sure the screen is in place, clean it also. If there is a collection or rust or dirt on the screen and in the bowl, the tank may need to be removed and cleaned.
Next get a clean glass ready. Remove the drain plug from the carb bowl and catch the contents. Again look for contamination.
With the plug still removed, open the fuel valve and let some gas flow through the open needle valve. You can LIGHTLY tap on the carb with a plastic screw driver handle while it is flushing.
Replace the plug, see if the flooding stops. If so, it was probably trash. If it continues the float may be sunk or the needle valve is worn, loose, or damaged.
If it persists, remove the carb, take it apart and see what's happening. Don't be afraid of it, they are simple and field serviceable. Just work over a clear surface so anything dropped doesn't get lost. Many times they can be eased apart without needing gaskets. Give the float the shake test, feel for gas inside one of the pontoons. Check the condition of the needle valve, be sure the seat is tight against the gasket, check the float level.
A simple test before putting it back together, turn the top upside down, suck on the fuel fitting, put your tongue over the hole. If it holds vacuum, it's good. No vacuum and it will still flood. Cleanliness is essential. If the tank is contaminated it will continue to trash the needle valve. Inline filters are not a good idea on gravity systems. Before reconnecting the fuel line, turn on the fuel, let the line flush out anything that might be on it's way down or that may have entered the line while it was disconnected. I like to let it slow trickle while making the connection.
Lots of how to information and specs online and on Youtube.
If your carb is original, and nothing broken, save it! Better quality than the aftermarket fit all's.

Today's Featured Article - Harvestin Hay: The Early Years (Part 2) - by Pat Browning. The summer of 1950 was the start of a new era in farming for our family. I was thirteen, and Kathy (my oldest sister) was seven. At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
