TRX350 Carburetor for Honda Rancher 350 - Complete Replacement Kit

In this review the TRX350 Carburetor kit is evaluated as a direct replacement for a range of Honda Rancher and Foreman ATVs. The bottom line: if you need a complete, inexpensive carb replacement that includes an air filter and oil filter and is sized for the TRX350 family, this kit delivers straightforward fit and improved running performance for aging four-stroke ATVs. It is best for owners who want a ready-to-install swap without sourcing separate parts.

Key Features

• Complete kit: Includes a TRX350 carburetor, air filter, oil filter, black throttle base cover, throttle base screw and fuel filter so you can replace multiple worn parts at once.
• Wide compatibility: Designed for Honda Rancher TRX350 models 2000-2006 and several Fourtrax and Foreman models, reducing the risk of fitment guesswork for common years listed.
• Direct replacement parts: Replaces factory part numbers 16100-HN5-673 and 16100-HN5-672 so it matches OEM reference points for easier sourcing.
• Balanced air/fuel sizing: Intake and air filter bore dimensions are specified to help restore proper mixture and engine response after installation.
• Easy installation: The kit is intended for plug-and-play replacement and includes small hardware to simplify the swap for home mechanics.

Who It's For

The kit is aimed at ATV owners and backyard mechanics who need a practical replacement for a failing carb on Honda Rancher 350 TRX350 models or compatible Fourtrax and Foreman machines. It is especially useful when the original carburetor shows poor idle, hard starting, or degraded throttle response and a single purchase with filter parts is preferred.

Owners who require an exact OEM branded component or who have highly modified engines may want to compare specifications carefully; professional tuners or late-model riders seeking factory-certified parts should consider OEM service dealers if they need guaranteed original-brand fitting or warranty paperwork.

Pros & Cons

Cons
