Question about Polaris ATV
The float or the float needle is the problem. Possibly during the changeover the carb was inverted or the seal on the needle could even have dried up inside if it was out of use for long. A speck of dirt or rust could be preventing the needle from closing.
Turn off the fuel, remove the fuel line to the carb, spray carb cleaner into the carb & drain it, spray again & drain again then hook it back up & try it running. Shut down immediately if it leaks & see below. If that fixes it, you're good.
Remember, FUEL is EXPLOSIVE. Allow things to air out once any fuel has been in the area as the fumes can lead to a tank some distance away!
There is a float needle you'll need to check to make sure it's sealing properly, or get a replacement. The dissasembly is pretty straight forward by viewing the part so I'll leave that to you. If you aren't familiar with the internal parts, you may want to get a manual for the schematic diagrams (check with the dealer the diagram probably comes with a carb rebuilld kit that includes gaskets & the float needle & seat) when you open this carburetor up you will find the float, it moves up & down with the fuel level & by doing so pushes the attached needle into the hole blocking the fuel intake(that is your main fuel line to the carb connection. The way the needle attaches or rides on the float is important & should be carefully noted prior to dissasembly. (Digital camera are helpful to review at no cost!) Really it's that simple.
The issue is, if the float sticks, or the needle leaks, you get fuel continuing to filll the carburetor as you've seen & it will come out of all of the openings eventually if the seal doesn't work or If it isn't set properly. Some of the floats are brass cans & they get holes in the solder or a bad seal, or there can be something small like a string, or speck of rust, in the fuel line sticking at the spot where the needle can't completely seal. Good luck

You have some bad seals and sounds like a sticking float or needle valve
Get the rebuild kit for the carb, give it a good cleaning, and replace the seals...that should fix ya right up
Most likely when your engine went bad some debris got thrown back into the intake and sucked into the carb.
