I have had that problem many times over the years with many carbs. 99.99% of the time it was a little garbage stuck in the float valve orifice. If it is something that showed up after you took the carb apart, it could be the adjustment of the float ear that pushes up on the little valve (addressed in other posts) and is out of adjustment. I have some numbers for manufacturer settings (measurements) to set the tab properly if that is the problem.
A new seat and float pin is inexpensive to pick up and replace. The seat must be installed properly. If the problem is a little dirt being stuck, I would make sure the fuel line is not flaking off pieces and replace it if needed. Also check for a missing or damaged screen in the fuel tank that could be allowing dirt to flow. I would recommend an inline fuel filter if you don’t already have one and be careful when installing or re-installing the filter. Sometimes a little flake of the hose or dirt will get knocked loose in the line. I like to install a fuel line shut off valve if not equipped and allow a little fuel to run through the line to purge it of debris prior to attaching the line to the carb. (allow to drain/flush into a catch pan..not the ground)
After all of that.....I am not sure how your engine is set up, but you want to make sure no fuel ran into your intake and into your cylinder when the float stuck open. This will contaminate your oil and ruin your engine. You can smell the oil and examine the level and viscosity to ensure that this has not happened. When in doubt, drain it out and start with new manufacturer recommended oil. Do the oil change only after you are sure you have your float problem fixed. My neighbor changed his oil three times before the carb was fixed. He is a medical doctor and is a little slow with engines. (He is not my Doc by the way)
I've seen a couple of engines with tight bearings and other major damage due to flooding carbs leaking fuel into the oil via the cylinder.
