I had issues with my1994 Polaris 300 4×4 ATV leaking gas so I had a guy rebuild the carburetor. After he gave it back it was idling so high I couldnt even get it in gear with out grinding so I took it to my neighbor (Yamaha mechanic) who has been tearing it all down trying to figure out wtf is going on.

The carb kit the 1st guy used was wrong and some of the needles were too long; he also bent the float arms for some reason. The neighbor wanted me to order a whole new carb. I have the part # 3130498 but I have only found 1 and it was almost $500.

Does anyone know the specs on the original carb and know where I can get one at a reasonable price? I keep seeing references to Mikuni but I have no idea what size bore, etc.
