If the float has recently been refinished, they do have a tendency to stick wide open. If you could wait a month or so to test it after refinishing that might not happen, but most of us don’t have that kind of time and patience. Eventually, the problem will go away with time and use.
In the meantime, keep a small piece of wire with you when you turn the fuel on. If the float sticks, and the carb starts dumping fuel, insert the wire into the needle guide on the carb cover, and tap the top of the float needle until it comes free and floats as it should. Also, light tapping on the bottom of the carb with a screwdriver handle/dowel/etc. will often free the float.
If I have a motor with a float that I suspect may stick, I will turn on the fuel, and then turn off the fuel immediately to fill up the bowl. If no leaks, then turn the fuel back on and you’re good to go.
