YAMAKATO Dual Tri-Fuel Carburetor for 170–224cc Generators — Predator/GX160 Fit, Gas/Natural Gas/Propane

YAMAKATO's Dual Tri-Fuel Carburetor is a direct-fit replacement that lets compatible small generators run on gasoline, natural gas, or propane with OEM-level performance.

This carburetor assembly is engineered as a swap-in replacement for a range of 170–224cc OHV generator engines, including Predator 3200–4375 and Honda GX160 clones. It is built to the dimensions and function of original equipment parts and includes non-asbestos mounting gaskets so you can convert or restore tri-fuel capability without fabricating adapters. The unit is intended for conventional (non-inverter) portable generators used in home backup, jobsite, and recreational settings; some mechanical familiarity is required for installation and proper gas regulator setup.

Will this carburetor fit my Predator or Honda GX160-style generator?

Many 196–224cc generator engines that share common mounting and throttle linkage patterns will accept this carburetor. Fitment depends on engine model, shaft orientation, and manifold spacing.

• Compatible with Predator 3200–4000 (and 3500–4375 peak) conventional generators.
• Designed for Honda GX160 clone engines used in many 170f/168f/170 and similar models.
• Fits select models from Champion, Generac, Firman, Ai Power, and Ironton—verify engine displacement and mounting before purchase.
• Includes non-asbestos gaskets to match manifold sealing dimensions on compatible engines.

How do I set it up for natural gas or propane operation?

This carburetor supports tri-fuel operation, but gas pressure and regulator selection are critical to safe, reliable performance. Confirm local codes and regulator specs before switching fuels.

• Natural gas pressure (PNG/CNG) should be regulated to about 0.29–0.37 psi before engine inlet.
• Propane (LPG) requires a low-pressure regulator set around 0.40–0.55 psi at the carburetor inlet.
• Install external regulators—natural gas typically has building regulators; propane needs a tank/regulator assembly.
• Basic mechanical skills and a pressure gauge are recommended to verify correct supply pressure and adjust idle/spark settings after installation.

What performance and quality can I expect compared to original parts?

The YAMAKATO replacement is produced to match OEM dimensions and operating characteristics, aiming for stable idling and throttle response across fuels. It is not marketed as a performance upgrade but as a practical replacement or conversion component.

• OEM-quality machining and seals intended for durability in portable generator duty cycles.
• Tri-fuel tuning provisions for gasoline, natural gas, and propane with appropriate adjustments.
• Supplied gaskets reduce the need for additional sealing materials during replacement.
• Suitable for conventional, non-inverter generators; not designed for inverter-specific carb setups.

Are there models or situations where this won’t work?

Not every generator with a similar displacement will accept this carburetor. Incompatibilities include inverter-specific engines, mismatched manifold spacing, or atypical throttle linkages.

• Not compatible with many inverter generator carburetor designs—verify your unit type first.
• Some Champion models only accept this part on particular 196cc/212cc/224cc variants—check your model number.
• Requires correct physical fit and throttle/choke linkage alignment; custom fabrication may be needed if dimensions differ.
• Proper regulator setup is essential; incorrect gas pressure will cause poor running or unsafe conditions.

Who is this for? The YAMAKATO Dual Tri-Fuel Carburetor is aimed at DIY-savvy owners of non-inverter portable generators who need a reliable replacement or want to convert a compatible gasoline generator to natural gas or propane. It suits contractors, homeowners preparing backup power, and small-fleet operators who can verify fitment, install external regulators, and perform basic carburetor adjustments. If you need a drop-in, OEM-dimension tri-fuel solution for Predator-style or GX160-clone engines, this kit provides the parts and gaskets to get you running.
