FAQ

This kit is commonly listed for Polaris ATV applications, including Trail Boss, Trail Blazer, Big Boss, Xplorer, Xpress, Sport Scrambler, and Sportsman models. Reported engine sizes in listings include 250, 300, 350L, 400, and 400L. Because web sources conflict on whether certain versions are for 2-stroke or 4-stroke machines, the safest match is to verify your original carburetor part number and your exact model/year/engine type before ordering.
The main cross-reference numbers consistently associated with this kit are 3130383 and 3130424. Some related listings also mention additional numbers in the same carburetor family: 3130425, 3130493, 3130498, 3130574, 3130642, 3130670, 3130709, 3130710, 3130957, and 3131301. Confirm the number stamped on your original carburetor or check your Polaris parts lookup for your exact model.
Common carburetor-related symptoms include hard starting, needing choke longer than normal, rough idle, bogging on acceleration, fuel overflow, hesitation under load, and poor throttle response. On older Polaris ATVs, these problems are often caused by varnish from stale fuel, clogged jets, a sticking float needle, or cracked fuel lines allowing air leaks.
For most ATV applications, this is a moderate repair for someone comfortable removing body panels and intake boots. Typical tools are screwdrivers, pliers, hose-clamp pliers, a small socket set, and possibly picks for fuel and vent lines. Plan on about 45 to 90 minutes if access is straightforward. Before removal, take photos of throttle cable routing, choke/enricher connection, fuel line placement, and vent hoses so the new carb goes back in the same way.
Drain old fuel, inspect the tank for debris, replace any brittle fuel lines, and install a clean fuel filter. Also check the intake boot and airbox boot for cracks, since vacuum leaks can mimic carburetor problems. If your machine sat for a long time, inspect the petcock and make sure the throttle cable moves freely and returns fully before starting the engine.
Yes. Even if the carburetor bolts on, final tuning may still be required depending on engine type, altitude, exhaust condition, air filter setup, and the jet size installed. Some kits are sold with extra jets, which is a clue that calibration can vary by application. After installation, check idle speed, throttle response, plug color, and whether the engine hesitates or runs rich before assuming the setup is finished.
