HOLATO PZ19 Carburetor Kit for 50–125cc ATVs & Pit Bikes — Black, 35mm Air Filter & Adjustable Mix

HOLATO PZ19 carburetor kit supplies a ready-to-fit replacement carburetor, 35mm air filter, throttle cable, grips and all essential fittings for many 50cc–125cc Chinese ATVs, go-karts and pit bikes.

This all-in-one kit collects the common service parts you need when replacing or upgrading a small-engine carb system. It’s built around a PZ19 carburetor with adjustable mixture and idle, and includes fuel line hardware, throttle components and hand grips so you can finish installation without sourcing additional pieces. The set aims to match many popular youth and small-displacement models from brands like TaoTao, Coolster, Apollo, Baja and others (not compatible with GY6 engines).

Will this kit fit my 50cc–125cc ATV or pit bike?

Compatibility covers a broad range of Chinese-made and many small-displacement models; the kit is designed for carb bodies using a PZ19 standard bore. Confirm fit by comparing your existing carburetor size, intake gasket shape and throttle cable routing before ordering.

• Common fits: 50cc–125cc TaoTao, Coolster, Roketa, SSR, Baja and similar models
• Includes intake manifold gaskets and O-rings for straightforward replacement
• Not suitable for GY6 engine platforms—verify engine type

What parts are included and why they matter?

The kit bundles the PZ19 carburetor with a 35mm air filter plus the small parts that frequently fail or are missing, so you replace the whole intake assembly at once. Having matched components reduces fitting headaches and helps get the vehicle running again quickly.

• PZ19 carburetor with adjustable air/fuel screw and idle screw for basic tuning
• 35mm air filter, fuel hose, three fuel filters and spring clips for secure connections
• Spark plug, inline shut-off valve (petcock), throttle cable, left/right grips and kill switch

How hard is installation and what tools or adjustments are needed?

Installation is aimed at mechanically comfortable riders and DIYers; the carburetor and hoses mount with basic hand tools. After fitting, you’ll want to set idle and fine-tune the air/fuel mixture for smooth throttle response and reliable starting.

• Basic tools: screwdrivers, pliers, socket set, and possibly a torque wrench
• Carb allows disassembly for cleaning and has accessible mixture and idle adjustments
• Replace intake gaskets and test for vacuum leaks after installation

What should I check before buying to ensure compatibility?

Compare physical dimensions and mounting points of your current carburetor and intake manifold to the photos and listing details. Confirm your machine’s engine family and throttle cable style to avoid mismatches.

• Measure bore size and flange pattern to match the PZ19 carburetor
• Check that your engine is not a GY6 variant and that manifold gaskets align
• Inspect throttle routing and hand grip type to match included cable and grips

This kit is for owners, mechanics and hobbyists who service small-displacement ATVs, pit bikes, pocket rockets and go-karts and want a single‑purchase solution for a worn or missing carburetor and associated intake parts. It’s especially useful for rebuilding older or used machines where multiple small components are degraded or missing, and for riders who prefer to perform routine tuning and maintenance themselves rather than sourcing individual pieces.
