FourTrax 300 Carburetor for Honda TRX300 TRX350 - OEM Fit

In this review the FourTrax 300 carburetor is evaluated as a direct replacement for a range of older Honda ATV models; it is aimed at owners who need a cost-effective, OEM standard carb that restores engine performance. The single biggest reason to buy is fit and compatibility: this unit is built to the same dimensions and mounting pattern as several original parts numbers so it installs without major modification. For riders needing a usable, ready-to-install carburetor for maintenance or repair, this product delivers straightforward functionality.

Key Features

• Direct replacement: Replaces multiple factory part numbers so buyers can match their original unit and avoid adaptation work.
• Wide model coverage: Fits many Honda FourTrax, Rancher and Foreman model years, reducing the risk of ordering the wrong carb for older ATVs.
• OEM standard build: Manufactured to exact OEM standards so the carburetor integrates with the engine and preserves fuel delivery characteristics.
• Complete kit: Arrives with air and oil filters plus a cleaning brush so installers have basic consumables ready for fitment and cleanup.
• Warranty support: The seller offers a 30 day return window and a 365 day quality warranty with free replacement for qualifying defects.

Who It's For

The carburetor is best for DIY mechanics and professional technicians maintaining or restoring Honda ATVs from the late 1980s through the mid 2000s, specifically FourTrax TRX300/TRX300FW, TRX250, Rancher TRX350 variants and Foreman TRX400/TRX450 models. If the original carb has failed, this unit provides the same mounting and fuel flow characteristics expected from an OEM part.

Owners who need factory-new performance for late-model ATVs not listed in the replacement fitment should look elsewhere, and those unfamiliar with carburetor plumbing may prefer professional installation since fuel line connections and float settings sometimes require experience.
