Which vehicles is this carburetor compatible with?

This PZ19 is designed for a wide range of small-displacement four-stroke quads, pit bikes and go-karts. It fits many 50cc, 70cc, 110cc and 125cc models produced by popular Chinese manufacturers—but it is not compatible with GY6 engines.

How is the PZ19 different from the PZ22 and what benefits will I notice?

Compared to the larger PZ22, the PZ19 is tuned for more economical fuel use and crisper throttle response on lightweight machines. Many riders notice improved mileage and more controllable low- to mid-range power, making it useful for daily riding and light trail use.

• Smaller bore design yields leaner fuel consumption than PZ22
• Improved throttle response, especially at low RPMs and during acceleration
• Manual air-mix and idle adjustments let you fine-tune performance

What comes in the kit and will I need extra parts?

The kit is packaged to be installation-ready for most applications, with filters, hoses and essential fasteners included. You may only need basic hand tools and possibly small consumables depending on the exact machine and condition of the intake manifold seals.

• PZ19 carburetor body plus 35 mm air filter and fuel hose
• Replacement fuel filters, clamps, gasket set and a small wrench included
• Extras: spark plug, oil switch and hardware for a complete swap

Is the 125cc version different and how do I operate the choke?

The 125cc PZ19 is supplied with a manual (hand) choke for straightforward cold starts. The hand choke provides simple, reliable control over enrichment during startup—adjust or turn off the choke once the engine runs smoothly.

• 125cc model uses a hand-operated choke lever for cold starts
• Idle speed and air–fuel ratio adjustable via accessible screws
• Follow warm-up procedure: engage choke to start, then gradually disengage

This carburetor is aimed at riders, mechanics and DIY enthusiasts who own small-displacement ATVs, pit bikes or go-karts and want a reliable, economical replacement or upgrade. If you need a bolt-in carburetor that improves fuel economy, delivers cleaner low-end throttle, and includes the consumables required for installation, the YOXUFA PZ19 kit is a practical choice—just confirm engine type and manifold fit before ordering.
