Yamaha ATV Carburetor Identification

I have a 2001 Yamaha Wolverine ATV. I have orderd a needle and seat for the carb multiple times by the VIN#. The parts have not fit.(JY4AHO4Y51A001880) I’m starting to think this is not the original carb for this ATV. The only numbers I can find on the carb are 4KB 10
K595.
Any help would be appreciated in finding the actual Yamaha part numbers for for these parts or the entire carb.
