YOXUFA PZ19 19mm Carburetor Kit for 50-125cc ATVs & Dirt Bikes — Includes 35mm Air Filter

The YOXUFA PZ19 is a 19 mm hand-choke carburetor kit designed to replace worn or damaged carburetors on a wide range of 50–125cc Chinese-built dirt bikes, ATVs, go-karts and mopeds.

This replacement carburetor arrives as a complete plug-and-play kit with a 35 mm air filter, fuel line and filter, gasket set and spark plug so you have the main wear parts needed to get your TaoTao, Coolster, Baja, SSR or similar mini bike or quad back on the trail. It’s engineered to match the PZ19 intake bore size and mounting pattern used across many 50cc–125cc small-displacement Chinese engines (not for GY6 engines), making it a common spare for owners and mechanics of budget off-road machines.

Will this carburetor fit my bike or ATV?

Compatibility is broad but specific: the PZ19 intake diameter, mounting bolt positions and throttle/shutter layout match many TaoTao, Coolster, Baja, SSR, Kazuma and similar models listed by manufacturers and parts sellers. Confirm your engine requires a 19 mm carburetor and compare the mounting face and throttle cable attachment before purchase.

• Fits many 50cc–125cc pit bikes, quads and mini choppers (examples in product fitment list)
• Check if your model is among TaoTao DB10–DB27, ATA-110/125, Coolster 70/110, Baja DR49/DR50/DR70 series
• Not suitable for GY6-style engines — verify intake bore and bolt pattern

What hardware and parts come in the YOXUFA PZ19 kit?

The kit is supplied with the carburetor plus the most commonly replaced consumables so you can install and start the engine without sourcing extra pieces. Spare gaskets and a new spark plug help ensure a clean seal and reliable ignition after installation.

• 1 x PZ19 hand-choke carburetor (19 mm intake)
• 1 x 35 mm air filter, 1 x red fuel hose, 1 x red inline fuel filter
• 1 x gasket set and 1 x spark plug included for immediate installation

How do I measure and install the PZ19 correctly?

Measure the carburetor intake and filter dimensions to confirm fit: inside diameter 19 mm, outer carburetor side diameter ~32 mm and air filter diameter 35 mm. Installation typically involves removing the old carburetor, transferring any usable cables or mounts, fitting the new gaskets, connecting the throttle and choke cables, and attaching the fuel line and filter.

• Verify intake bore is 19 mm and filter stem is compatible with 35 mm filter
• Install new gaskets and tighten mounting bolts evenly to avoid air leaks
• Prime fuel, inspect for leaks, then adjust idle/mixture per engine manual

What benefits does replacing my carburetor with this kit provide?

Replacing an old or clogged carburetor with a complete kit restores consistent fuel delivery and makes tuning easier, often improving cold starts and throttle response. The included consumables reduce downtime and the need to hunt for smaller parts after the swap.

• Complete kit reduces parts sourcing — filter, fuel hose and gaskets included
• Hand-choke design simplifies cold starts for carbureted small engines
• Restores reliable fuel flow and makes basic tuning more predictable

Who is this for: The YOXUFA PZ19 kit is aimed at owners, hobby mechanics and small repair shops working on Chinese-manufactured pit bikes, ATVs, go-karts and mopeds in the 50–125cc range who need an OEM-style carburetor replacement. If your machine uses a PZ19-sized carburetor and you want a ready-to-install package with the common consumables included, this kit is a practical, cost-effective choice. Always confirm model compatibility and measurements before ordering to ensure proper fit and operation.
