Carburetor Carb for Honda Fourtrax TRX300 TRX350 TRX400 TRX450 TRX350

In this review the reviewer tested the ATRACYPART carburetor designed to replace several Honda Fourtrax, Foreman and Rancher stock units and found it to be a practical, cost-effective replacement for owners who need dependable performance and a close OEM fit. It is best for DIY mechanics and ATV owners who want a straightforward swap to restore power and throttle response, and the single biggest reason to buy is that it restores smooth running and torque without a complex rebuild or expensive OEM part.

Key Features

• High performance: The carb delivers reliable throttle response and restored engine torque so the ATV feels more responsive under load.
• OEM fit: Built to match original mounting and bore dimensions so it fits the listed Honda Fourtrax, Foreman and Rancher models with minimal modification.
• Precision mixing: Manufactured to production standards intended to keep the fuel and air mixture consistent for smoother idling and less stumbling.
• Clear sizing: Includes concrete intake and air filter side diameters so buyers can confirm compatibility before installation.
• 12-month warranty: A year of coverage offers buyers straightforward replacement or refund support if the unit fails.

Who It's For

This carburetor is for owners of 1993-2000 Honda TRX300FW, 1986-1987 TRX350 Fourtrax, 1997-2004 TRX400FW Foreman, 1998-2004 TRX450 variants, and 2000-2006 TRX350 Rancher who want a direct-replacement part that restores drivability without rebuilding the original. It fits riders who are comfortable performing basic installation and minor adjustments when needed.

It is not the right choice for someone who needs an exact OEM-branded part number for warranty transfer, or for users who expect a plug-and-play electronic heater connection where that was not present; some buyers reported electrical connection and fuel leakage issues that may require attention after fitting.

Pros & Cons

• Runs great out of the box for many customers, restoring smooth idle and throttle response.

• Strong value compared with buying a full OEM replacement, and backed by a 12-month warranty.

Cons

• Some users reported fuel leakage which requires careful inspection and possible gasket or float adjustments during installation.
• Occasional incorrect electrical heater connection reported, so check connections before first start.
