This is a brand new carburetor from speedparts-star, designed to fit a wide range of Polaris Sportsman ATVs – the 300, 335, 400, 450, 500, 600, and 700 models, including MV7 and 4x4 variants.
It's a direct replacement for OEM part numbers 1203059, 1253436, and 3130904.
If your Sportsman is hard to start, idles rough, boggs down, or guzzles fuel, a worn-out carb is often the problem.
This new one comes ready to bolt on – no rebuild needed.
