Product Overview
An ATV that needs choke to stay running, floods after parking, stumbles off idle, or loses power can have varnish, diaphragm damage, float wear, or blocked passages. Petcock flow, tank vent, intake boot, valve clearance, compression, and ignition should be checked first.
The 325 and 330 use related but model-specific calibrations. Match the old carburetor, BST-style body, cable and choke, boots, ports, jet sizes, and original numbers such as 3131571.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, electrical or fuel-system version, dimensions, installed options, and previous repairs can affect fitment. Compare the original part and application information before purchase.
Frequently Asked Questions
Q: Can one carburetor cover both the 325 and 330 without adjustment? A: Physical fit may overlap, but jetting and setup must match the engine and elevation.
Q: Why does the engine die when the choke is pushed in? A: A restricted pilot circuit, low fuel level, weak supply, or intake leak can make the normal mixture too lean.
Q: How do I confirm fitment before ordering? A: Match the original reference number where available, then compare the removed part, dimensions, connections, mounting details, model, serial or production information, and package photos.
Q: Is this an original-equipment part? A: No. This is a new aftermarket part. Brand names and reference numbers are used only to identify compatible applications.
