YOXUFA PZ19 19mm Carburetor Kit for 49–125cc Bikes & ATVs — Cable Choke, Includes Filter and Gaskets

The YOXUFA PZ19 is a 19mm cable-choke carburetor kit designed to replace worn carburetors on 49–125cc Chinese mini bikes, ATVs, go-karts and mopeds for improved throttle response and reliable starting.

This all-in-one replacement carburetor arrives with matching intake parts and consumables so you can swap a tired or damaged carburetor quickly. Built to fit a wide range of small-displacement machines from brands like TaoTao, SSR, Kayo and Loncin, the PZ19 saves you time hunting down individual gaskets, fuel lines and filters. The kit’s measured diameters and included hardware make it a straightforward upgrade for common mini-bike and ATV engines that use a 19mm carb bore (not compatible with GY6 engines).

How do I know if the PZ19 will fit my bike or ATV?

Confirm fit by checking the carburetor mounting and intake diameters on your machine. The PZ19 has a 19mm carburetor bore, a 32mm outer intake flange diameter (air filter side), and a 35mm air filter diameter; it’s designed for many 49–125cc Chinese-style platforms.

• Carb bore: 19mm
• Intake outer diameter: 32mm
• Air filter diameter: 35mm
• Not compatible with GY6 engines

What comes in the kit and why does it matter?

The package includes the carburetor plus the key small parts you’ll need for installation and first use, so you won’t need to source separate hoses, clamps or a filter. This reduces downtime and ensures the carburetor seals and fuel path are fresh and matched to the unit’s dimensions.

• 1 × PZ19 cable-choke carburetor
• 1 × red air filter and corresponding hose pieces
• 1 × red fuel line, 2 fuel filters and 4 clamps
• Complete gasket set and a spark plug included

How will installing this carburetor affect performance and maintenance?

Replacing a worn carburetor can restore starting consistency, reduce stalling and improve throttle response under load, especially when original jets and seals have aged. The cable choke style gives a familiar manual operation for vintage-style or utility small engines, and the included consumables simplify routine maintenance after installation.

• Restores reliable idle and cold starting
• Manual choke for straightforward control
• Fresh gaskets and fuel filters prevent leaks and contamination
• Includes clamps and line for a tidy install

Is the YOXUFA PZ19 easy to install for a weekend mechanic?

Yes—if you have basic hand tools and a working knowledge of carburetor connections, this kit is designed for bolt-on replacement without major modifications. Follow vehicle-specific instructions for throttle/cable routing, fuel line connection and choke cable attachment to avoid issues.

• Basic tools: screwdrivers, pliers, wrench set
• Requires routing throttle and choke cables correctly
• Connect included fuel line and clamps securely
• Check for vacuum/air leaks after installation

Who this product is for: The YOXUFA PZ19 kit is aimed at owners and mechanics of mini dirt bikes, pit bikes, small ATVs, go-karts and mopeds using 49–125cc Chinese-style powertrains who need a direct-style replacement carburetor with matching intake hardware. It’s particularly useful for riders maintaining older machines, shops that service a range of small-displacement vehicles, and DIYers who prefer to replace the entire carburetor and related consumables at once.
