YAMAKATO Huayi P22-4-H Carburetor for Champion Dual-Fuel Generators — Includes Gaskets & F6RTC Jet

YAMAKATO’s Huayi p22-4-h carburetor is a direct-fit replacement designed to restore fuel delivery and idle stability on a wide range of Champion and other dual-fuel generators.

If your dual-fuel generator is sputtering, hard to start, or idling poorly, the carburetor is often the culprit. This YAMAKATO Huayi unit (part numbers p22-4-h / 27.131000.05 / 27.131000.08) replaces worn or clogged factory carbs on specified Champion models and is also compatible with select Firman, Honda, Predator, Westinghouse, Ducar, and Wen generators. The package includes the carburetor plus three gaskets and an F6RTC jet, so you have the key components needed for a clean swap.

Which generators will this YAMAKATO Huayi carb fit?

This carburetor is built for a range of Champion dual-fuel generator models and cross-compatible with several other brands that use the Huayi p22-4-h design. Confirm model numbers before ordering to ensure fit — it will not replace the visually similar p22-7-h.

• Compatible Champion models: 76533, 100122, 100238, 100397, 100456 (covers specific power ratings listed in product specs).
• Also fits many Firman, Honda, Predator, Westinghouse, Ducar, and Wen units using Huayi p22-4-h.
• Not compatible with Huayi p22-7-h (27.131000.13) despite similar appearance.

How easy is it to install the replacement carburetor?

Installation is straightforward for anyone comfortable with basic small-engine maintenance. The carb ships with three gaskets and a replacement F6RTC jet to simplify the swap and help ensure a proper seal and correct fuel flow.

• Remove the air filter and disconnect fuel lines before unbolting the old carb.
• Use included gaskets to prevent vacuum and fuel leaks when mounting the new unit.
• Reinstall fuel lines and test run to verify idle and throttle response.

What performance improvements can I expect after replacement?

Replacing a worn or clogged carburetor typically restores consistent starting, steadier idle, and more reliable throttle response under load. While this part addresses fuel delivery issues, overall generator performance also depends on spark plug condition, air filter cleanliness, and correct fuel mixture.

• Smoother cold starts and fewer stalling events at idle.
• More consistent RPM under varying loads and improved throttle responsiveness.
• Supplied F6RTC jet helps ensure proper fuel metering for the compatible models.

What comes in the YAMAKATO replacement carburetor package?

The kit includes everything you need to swap the carburetor and help avoid a second trip for small parts. It’s packaged to reduce downtime and make installation quicker.

• 1x YAMAKATO Huayi carburetor (p22-4-h / 27.131000.05 / 27.131000.08).
• 3x gaskets for intake and mounting surfaces.
• 1x F6RTC jet installed or separately included as needed.

Who is this for: This carburetor is aimed at owners and technicians maintaining Champion dual-fuel generators (and compatible models from other brands) who need a direct-fit replacement to fix fuel delivery problems. It suits DIYers comfortable with basic engine work and repair shops that service portable generators and want a reliable Huayi-part substitute with the necessary gaskets and jet included.
