ANTO Carburetor 951-14423 5X65RU/5X65A for Cub Cadet, Troy-Bilt, MTD Lawn Mowers

Reliable replacement carburetor for a wide range of lawn mowers

When your mower stalls, misfires, or idles unevenly, a replacement carburetor can help restore a steadier engine cadence and smoother throttle response. The ANTO carburetor model 951-14423 with 5X65RU and 5X65A design aims to provide a dependable option that’s ready to install in several popular mowers. It’s cast from quality materials, with precise seals and a compact form that fits in tight engine bays. This unit is presented as a direct-fit replacement rather than a rebuild task, helping you return to routine mowing without extended downtime. The kit emphasizes straightforward fit and consistent performance, with components designed to work together to support reliable fuel delivery.

Broad compatibility for popular mower lines

Compatibility and fit across brands is a key consideration. The carburetor is described as compatible with Cub Cadet LE100, SC100 hw, SC300, SC500, and ST100 lines. It also lists compatibility with MTD RM120, RM210, RM220, RM2210 models and Troy-Bilt TB105, TB120, TB220, TB115, TB270. The breadth means many older and newer mowers can use this part as a standard replacement option when original parts are scarce or discontinued. While model-by-model checks are advised, this unit offers a practical route to restoring a mower’s fuel delivery without chasing multiple parts.

• Direct-fit replacement for multiple Cub Cadet, MTD, and Troy-Bilt models
• Designed to help restore starting reliability and smoother idle
• Durable cast components and seals for longevity
• A complete replacement kit is included for convenience

What’s in the kit

Every order provides a ready-to-install assembly with essential components included, so you can complete the replacement in a single session.

• 1 carburetor (951-14423)
• 1 spark plug
• 1 fuel line
• 4 gaskets
• 1 fuel filter
• 4 clamps

In real-world use, this replacement can help restore cleaner burning and more predictable engine behavior during mowing sessions, especially after storage or long periods of inactivity. The assembly’s compact geometry supports installation in constrained engine bays, while the included hardware reduces the need to source parts separately.

Note that results can vary with the overall condition of the mower’s fuel system. Consider this option as a practical upgrade for restoring fuel delivery consistency rather than a guaranteed performance fix. For best results, pair with routine maintenance and clean fuel.
