SHIQINHA PZ20 Carburetor and Complete Wiring Harness Kit for 70–125cc ATVs — Fits Taotao Coolster Kazuma with Ignition Coil & CDI

SHIQINHA's PZ20 carburetor plus full wiring-harness kit replaces worn fuel and electrical parts on many 70–125cc Chinese 4-stroke ATVs, restoring reliable starting, smoother throttle response, and cleaner fuel delivery in one swap.

If your small-displacement quad stalls, idles rough, or has flaky electrics, replacing isolated parts can be frustrating and time-consuming. This kit bundles a PZ20 carburetor, intake components, and a complete electrical harness (stator, ignition coil, CDI, solenoid relay, starter relay and wiring assemblies) so you can refresh both fuel and ignition systems at once. The components are designed for popular Chinese ATV models and are intended as direct-fit replacements to reduce installation guesswork.

Which machines will this kit work with?

The SHIQINHA kit covers a broad range of 70–125cc Chinese 4-stroke ATVs from common brands. It lists known compatible models so you can quickly verify fit before ordering.

• Fits many Taotao, Coolster, Kazuma, Baja, Roketa, Icebear, Vitacci and other Chinese-brand 70–125cc quads.
• Compatible with specific TaoTao model numbers (ATA-110 series, ATA-125 variants) and numerous Coolster 110/125 models.
• Works for engines that use a PZ20-style carburetor and the shown stator/ignition plug pattern.
• Always compare photos of the stator, connectors, and intake manifold to your bike before purchase.

How does the PZ20 carburetor change performance?

The PZ20 is sized and jetted to deliver a more responsive throttle compared with smaller PZ19 units while avoiding the excess fuel consumption sometimes seen with larger PZ22 types. It helps provide brisk acceleration without dramatically raising fuel use.

• Includes a precision-jetted carb for a balanced air-fuel mix under load.
• Comes with a 35mm air filter and intake manifold for a complete fuel-side swap.
• Designed to reduce hesitation and improve throttle snap during acceleration.
• All necessary fuel lines included for a single install package.

What electrical parts are included and why replace them together?

The harness package consolidates the stator, ignition coil, CDI, relays and multi-function switch into a matched assembly. Replacing the entire set eliminates mismatched components and common failure points that cause hard starts or intermittent power loss.

• Complete wiring harness with factory-style connectors and routing for simplified installation.
• Stator and ignition coil supplied to ensure correct timing and charging output.
• Includes starter relay and solenoid to resolve starting circuit problems.
• Modular assembly reduces brittle splices and improves reliability on rough terrain.

How easy is installation and what should I check first?

This kit is intended as a direct replacement for the listed ATV models, but installation skill varies. Basic mechanical and electrical familiarity is helpful; the kit includes the parts you need to replace both fuel and ignition systems in a single project.

• Confirm connector styles and stator shape match your ATV photos before buying.
• Basic hand tools, a service manual reference, and time for testing are recommended.
• Replacing both systems at once minimizes downtime compared with piecemeal repairs.
• If unsure, a local small-engine technician can complete the swap in one service visit.

Who is this for? This SHIQINHA bundle is aimed at owners of 70–125cc Chinese-engine ATVs who want a single, comprehensive repair solution for persistent fuel delivery and electrical problems. It suits DIY mechanics who prefer a one-stop replacement to troubleshooting multiple suspect parts, as well as shop technicians looking for a matched parts set to speed repairs. Before ordering, check the included photos and your machine’s model and connector types to ensure compatibility.
