HIAORS PZ30 30mm Carburetor for 150–300cc CG 4-Stroke Engines — Aluminium Body, Improved Low-Mid Throttle

The HIAORS PZ30 is a 30mm replacement carburetor designed to restore smoother starts, steadier idling, and better low-to-mid throttle response on many 4-stroke 150–300cc motorcycles, ATVs, pit bikes and go-karts.

If your machine suffers from hard starting, inconsistent idle, poor throttle response, or higher fuel use due to a worn or mismatched factory carburetor, the PZ30 offers a direct, affordable swap. Built from rust-resistant aluminum with brass wear parts and sealed fittings, this carb balances fuel and air for improved everyday performance without complicated jetting for many popular CG-style engines and models from brands like TaoTao, Apollo, Lifan and Zongshen.

Which machines will the PZ30 carburetor fit?

The PZ30 fits a wide range of CG-style 4-stroke 150–300cc engines found on pit bikes, ATVs, quads, go-karts and small motorcycles. It is not compatible with GY6 engines. Check your intake manifold size and throttle linkage before ordering.

• Designed for CG 150cc–300cc 4-stroke engines and similar setups
• Common compatible models: XR200 variants, TaoTao, Apollo, Baja, Loncin, Lifan, Zongshen
• Works for pit dirt bikes, quads, go-karts and small motorcycles
• Not suitable for GY6 engine families

How does the PZ30 improve engine behavior?

Precision machining and a 30mm bore help the PZ30 deliver a more consistent air–fuel mixture compared with degraded stock carbs. The result is easier cold and hot starts, steadier idling and stronger throttle response in low and mid rpm ranges without aggressive modification.

• Better mixture metering for smoother startup and idle stability
• Improved low-to-mid acceleration feel and throttle control
• Reduced fuel waste from leaking or worn factory carburetors
• Sealed components and brass wear parts resist corrosion and wear

What materials and construction features ensure reliability?

The body is cast from lightweight, rust-resistant aluminum for durability and heat tolerance. Critical moving parts use wear-resistant brass and sealing rings to limit leaks and fuel dilution, making the carburetor resilient under varied riding conditions.

• Aluminum alloy main body: light, corrosion-resistant and durable
• Brass internal components for wear resistance and longevity
• Sealing rings to prevent fuel leakage and maintain consistent pressure
• Simple design for easier maintenance and longer service life

Is the PZ30 difficult to install or tune?

The PZ30 is built for straightforward installation as a replacement carburetor on compatible machines. Basic tools and mechanical knowledge are usually enough; minor jet or idle adjustments may be needed to match local altitude, fuel quality, or exhaust modifications.

• User-friendly mounting layout for quick swap with many CG-style carbs
• Typical installation requires basic hand tools and hose connections
• Simple idle and mixture adjustments possible without specialty tools
• May require jet changes for high-altitude or heavily modified engines

Who is this for: Riders, mechanics and hobbyists who need a robust, cost-effective replacement carburetor for 150–300cc CG-style 4-stroke engines. Choose the HIAORS PZ30 if you want to restore reliable starts, stabilize idle, and improve everyday throttle response on pit bikes, ATVs, quads or go-karts from popular budget brands—without replacing the entire engine or exhaust system.
