BlueStars PZ22 Carburetor Kit 22mm for 50–125cc Pit Bikes & ATVs — 38mm Air Filter, Right-Side Choke

BlueStars PZ22 Carburetor Kit is a complete 22mm replacement carburetor assembly designed to fit many 50cc–125cc 4-stroke pit bikes and ATVs, supplied with filter, intake hardware, fuel fittings and a spark plug.

This kit supplies the core parts needed to restore fuel delivery on small Chinese 4-stroke engines where the original PZ22-style carburetor has failed or been removed. The package includes the PZ22 carb with a right-side hand choke, a 38mm conical air filter, intake pipe, fuel line, two fuel filters, clamps, gaskets and a spare spark plug so you can install and run quickly. Construction uses lightweight aluminum alloy for corrosion resistance and durability, and the air filter uses a double steel mesh to trap grit without restricting airflow.

How does this carburetor improve engine performance?

The PZ22 design restores the correct air-fuel mixture for small-displacement four-stroke engines, reducing issues like hard starting, rough idling, and excessive exhaust. Properly matched jets and flow diameter help the engine respond smoothly from idle to throttle. It is not a tuning part for power increases but a reliable direct-replacement to return factory-style operation.

• 22mm intake bore for consistent fuel atomization and airflow.
• Right-side hand choke for easier cold starts on many bike models.
• 38mm conical air filter with double steel mesh for improved particle filtration.
• Complete hardware included for faster installation.

Will this kit fit my SSR, TaoTao, Coolster or similar 4-stroke bike?

The BlueStars PZ22 kit is compatible with many 50cc–125cc Chinese 4-stroke pit bikes, quads and small ATVs that use a PZ22-style carb with a 48mm bolt center and a right-side hand choke. Always compare the intake inner diameter (22mm), bolt center spacing (48mm) and air filter outer diameter (38mm) against your original parts before ordering. If your OEM carburetor differs in size or choke orientation, this kit may not fit without modification.

• Check intake inner diameter: 22mm.
• Verify bolt hole center-to-center distance: 48mm.
• Confirm air filter outer diameter: 38mm.
• Right-side hand choke required for direct swap.

What comes in the box and what tools will I need?

The kit arrives with the carburetor and all installation consumables so you can replace the unit in one service session. Basic hand tools and a few minutes of mechanical familiarity are usually enough, though some models may require slight adjustments for an airtight intake fit. The package note reminds buyers to double-check part dimensions and images before purchasing.

• Included: PZ22 carb, 38mm air filter, intake pipe, fuel line, 2 fuel filters, 4 clamps, gaskets, spark plug.
• Tools: screwdrivers, pliers, socket or wrench set, and optionally carb cleaner.
• Time: expect roughly 30–90 minutes depending on bike accessibility.
• Tip: inspect throttle and choke cables for smooth operation while reinstalling.

How durable is the BlueStars kit and what warranty is offered?

The main carburetor body is machined from aluminum alloy to resist corrosion while keeping weight low. The air filter’s double steel mesh offers extended life versus foam-only elements, and included clamps and gaskets are sized for a secure seal. BlueStars backs the product with a lifetime protection policy covering manufacturing defects—check seller terms for claim steps.

• Aluminum alloy body for strength and corrosion resistance.
• High-density double steel mesh air filter for long service life.
• Complete gasket set to ensure reliable sealing after installation.
• Lifetime protection for defects per seller policy.

It's ideal for riders restoring a machine, repairing a damaged carburetor, or replacing worn components to eliminate starting, idling or fuel delivery problems. Confirm measurements and choke orientation before purchase to ensure compatibility.
