ATRACYPART PZ19 19mm Carburetor Kit for 49cc–125cc Mini Bikes & Quads — Includes Air Filter, Throttle Cable

If your small-displacement 4-stroke engine runs rough, stalls, or won’t reach full throttle, the PZ19 carburetor kit from ATRACYPART provides a direct-fit alternative to worn or damaged OEM carbs for a wide range of Chinese and import mini bikes, quads and pit bikes. The assembly is built for horizontal engine intake ports and includes the essential mounting hardware, fuel line and an air filter so you can swap it in with minimal modifications.

Which machines is this PZ19 carburetor compatible with?

What are the key measurements and mounting details I need to check?

Before purchasing, verify three critical dimensions: the engine opening outer diameter, the filter side diameter, and the bolt-hole spacing. These determine whether the carb will seal properly and line up with your engine’s intake and mounting studs.

• Engine Intake Opening O.D.: 19mm (0.75 inch).
• Air Filter Side: 37mm outer / 33mm inner diameter.
• Bolt Hole Spacing (engine side): 48mm center-to-center (1.89 inch).
• Designed for horizontal intake ports and hand-choke configurations.

The ATRACYPART kit ships as a ready-to-install package including the carburetor, an air filter, fuel line, fuel filter, gasket set, throttle housing, throttle cable and grips. Installation is intended as a direct replacement on compatible machines and typically requires basic hand tools and minor adjustments to idle and mixture screws after mounting.
