YOXUFA PZ19 19mm Carburetor with Cable Choke for 49–125cc ATVs Pit Bikes Go-Karts — Complete Kit with Air Filter & Spark Plug

YOXUFA PZ19 is a 19mm cable-choke carburetor kit designed to replace worn carburetors on a wide range of 49–125cc Chinese mini ATVs, pit bikes, go-karts and mopeds.

This complete carburetor assembly arrives with a red foam air filter, fuel line, inline filters, clamps, gasket set and spark plug — giving you the majority of parts needed for a quick swap on compatible machines. It fits many popular makes and models commonly used in small-displacement off-road and recreational vehicles; measurements and compatibility notes are included so you can confirm fit before ordering.

Which machines will this PZ19 carburetor work on?

The YOXUFA PZ19 is engineered for small-displacement engines used in mini ATVs, pit bikes, go-karts and scooters. It fits several 49cc–125cc models from brands like Tao Tao, Baja, SSR, Kazuma, Loncin, Sunl, Roketa and others, but not GY6 engines. Always cross-check your engine family and inlet sizes before installation.

• Compatible with many Tao Tao, Baja, SSR and Kazuma 50–125cc models.
• Includes exact diameter specs to verify physical fit: 19mm carb bore.
• Not compatible with GY6-style engines—measure before buying.

How does the 19mm cable choke affect performance and tuning?

The 19mm bore and cable-choke design control the air–fuel mixture during cold starts and throttle transitions, offering predictable response for low-displacement engines. It’s suitable for stock or mildly modified setups where a direct replacement or simple upgrade is required. Fine tuning (jetting and idle adjustment) may still be necessary to match altitude, fuel quality, or aftermarket exhaust and intake changes.

• 19mm bore for small-displacement single-cylinder engines.
• Cable-actuated choke for consistent cold-start behavior.
• Adjustable idle and jetting possible to optimize mixture.

What parts are included and what tools or steps are needed for installation?

This kit ships with a carburetor and common consumables so you can perform a straightforward replacement without sourcing extra parts. Typical installation requires basic hand tools and roughly 30–90 minutes depending on your experience. Inspect gaskets, clamps and the fuel line routing during installation to ensure leak-free operation.

• Package contains carburetor, red foam air filter, fuel line, two fuel filters, four clamps, gasket set and a spark plug.
• Basic tools: screwdrivers, pliers, wrench set and possibly a carburetor cleaner for prep.
• Recommend checking throttle and choke cable routing and sealing all hose connections.

How do I confirm fitment for my vehicle?

Measure the carburetor inlet and mounting pattern on your machine and compare to the kit’s provided dimensions before purchase. The most important measurements are the carb bore (19mm) and the outer diameters listed for the airbox and filter connection. If your vehicle uses a GY6 engine or has an incompatible flange, this carburetor will not fit.

• Verify carburetor inside diameter: 19mm bore.
• Check outer/filter-side diameters: 32mm and 35mm where specified.
• Confirm mounting holes and throttle/choke cable compatibility on your engine.

Who is this for: The YOXUFA PZ19 kit is aimed at owners and mechanics of small-displacement off-road vehicles, pit bikes, go-karts and mopeds who need a direct replacement or an affordable upgrade for a worn or damaged carburetor. It’s best for people comfortable checking fitment dimensions and performing basic mechanical work; racers or heavily modified engines may require additional tuning or different carburetor specifications. If you’re unsure, measure your current carburetor and compare to the kit specs or consult a mechanic before purchasing.
