Butom GX390 Carburetor for Honda GX340 GX390 Engines – All-In-One Kit with Fuel Filter & Gasket

Unlock dependable fueling with the Butom GX390 Carburetor

The Butom GX390 carburetor is designed to work with Honda GX340 and GX390 engines, covering 11 to 13 HP configurations. This replaceable unit is presented as an all-in-one kit, delivering a practical solution for reliable maintenance and quick swaps on outdoor power equipment.

Compatibility and fit

Engine compatibility spans Honda GX340 and GX390 families, including select Toro models such as the 22308 Dingo Tx 413 and 22330 Tx 413 Compact Utility Loader. This broad compatibility helps streamline choices when you manage a fleet of machines or a single versatile engine lineup.

Note that it replaces several part numbers including 16100-ZF6-V01, 16100-ZF6-V00, 16100-ZF2-V00, and 16100-ZF2-V01, offering a drop-in option for many compatible setups.

All-in-One Kit and included components

• Butom 16100-ZF6-V01 carburetor
• Fuel tank joint fuel filter
• Fuel filter
• Spark plug
• Gasket set (three gaskets)

The kit is designed to be convenient from the start, reducing the need to source separate parts. This can save time and simplify maintenance across different machines that share engine families.

Premium construction for durability

Durability is reinforced by thoughtful materials: brass components resist heat and corrosion, a zinc plated float bowl guards against rust, a high-density plastic float maintains stable fuel control, and an anodized aluminum carburetor body adds rigidity for tough jobs.

• Withstands heat, corrosion, and wear in daily use
• Brass and brass-adjacent parts promote long-term reliability

Out-of-the-box readiness

Expect a factory-tuned setup for quicker installation and smoother startup. Wet flow testing is used to emulate real-world engine conditions, providing a realistic baseline for performance as you swap parts on your equipment.

Dimensions and fit considerations

Key measurements to verify before installation include a 51 mm mounting hole distance (center to center), a 27 mm throttle diameter, a 30.5 mm choke diameter, a 21 mm venturi, and a 5 mm fuel inlet line. Aligning these helps optimize compatibility with GX340 and GX390 layouts.

In real-world use, users may notice easier maintenance cycles, fewer carburetor-related issues, and smoother engine operation when the kit is employed as part of routine service. Outcomes can vary with equipment age and usage, but the kit provides a solid foundation for dependable carburetion.
