YOXUFA PZ19 19mm Carburetor Kit for 49–125cc ATVs & Pit Bikes — Red Air Filter, Fuel Lines & Spark Plug

YOXUFA PZ19 carburetor kit is a complete replacement cable-choke carburetor assembly designed to restore reliable fueling to 49–125cc Chinese ATVs, pit bikes, go-karts and mopeds.

If your small-engine ATV, quad, dirt bike or cart is running rough, flooding, or hard to start, a worn or clogged carburetor is often the cause. This YOXUFA PZ19 kit bundles the 19mm carburetor body with a red air filter, fuel lines, clamps, fuel filters, gasket set and a spark plug so you get the core parts needed to replace the carburetor and related consumables in one swap. Dimensions and fitment cover the most common Chinese mini-bike and ATV models, but it's important to check measurements and compatibility before ordering.

Will this carburetor fit my 110cc or 125cc ATV?

The PZ19 is made to fit many 49–125cc Chinese engines used across popular brands. Fitment lists include TaoTao, Baja, SSR, Kazuma, Loncin, Sunl, Kayo and more, which covers common 70–125cc ATVs and mini bikes. Confirm the carburetor inside diameter (19mm) and air filter outer dimensions against your existing unit to ensure a match.

• Carburetor inner bore: 19 mm
• Outer carb throat where air filter mounts: 32 mm
• Air filter outer diameter: 35 mm
• Not compatible with GY6 engines

What parts are included and how does that help installation?

This kit supplies the carburetor plus consumables you normally replace at the same time, so you avoid extra trips for small parts. The included red air filter, fuel hose, two fuel filters, clamps, gasket set and spark plug let you reseal fuel and intake connections and finish the job cleanly. That reduces leaks and simplifies setup for a fresh tune and idle adjustment.

• 1 x PZ19 cable-choke carburetor body
• 1 x red foam air filter and adapter
• 1 x fuel line plus 2 fuel filters and 4 clamps
• 1 x gasket set and 1 x spark plug for reassembly

How do I verify compatibility before buying?

Measure your current carburetor throat diameters and compare with the kit specs: 19mm inside bore, 32mm outer throat, 35mm air filter diameter. Cross-check your vehicle model against the compatibility list, and note this product is built for many Chinese-made mini ATVs, pit bikes and go-karts but excludes GY6 engines. If you have questions about a specific model, compare images and dimensions before purchase.

• Check your carburetor bore equals 19 mm
• Confirm the air filter mounting diameter is approximately 32–35 mm
• Match your vehicle to listed brands and models in the product description
• Read the gasket and mounting flange shape against your old carburetor

What should I expect after installing this carburetor?

With correct installation and tuning, the PZ19 kit typically improves throttle response, starting consistency and reduces fuel leakage caused by old seals. You may need to adjust idle and main jets slightly to match altitude, fuel grade and exhaust condition. Keep periodic checks on clamps and the foam filter to preserve performance and avoid dirt ingestion.

• Throttle response and cold starts should feel more consistent
• Replace foam filter regularly for lasting performance
• Minor jetting adjustments may be required for peak running

Who is this for: Riders, DIY mechanics and small-vehicle fleet maintainers who need an affordable, all-in-one carburetor replacement for Chinese-made 49–125cc ATVs, dirt bikes, go-karts and mopeds. This kit is ideal if you want the main carburetor body plus all common small parts (filters, fuel line, clamps, gaskets and a spark plug) to complete a straightforward rebuild. Always confirm the 19mm bore and mounting dimensions match your existing carb before ordering.
