MOTOALL Carburetor PZ19 19mm for 50–125cc ATVs and Dirt Bikes — 35mm Air Filter Included, Bolt-On Replacement

MOTOALL PZ19 19mm carburetor with included 35mm air filter and necessary gaskets is a direct-replacement carb designed to fit many Chinese 50–125cc ATVs, dirt bikes and go-karts.

This compact carburetor assembly replaces worn or damaged stock units on small-engine recreational vehicles. Built with a 19mm engine opening and a 35mm air filter mounting, it’s intended as a bolt-on option for many Chinese-manufactured 50cc–125cc machines. The kit ships with the carburetor, air and gas filters, screws, gasket and O-ring so you have the common installation parts in one package. Always confirm your existing part numbers and compare the photos to ensure compatibility before installation.

Will this MOTOALL carburetor fit my bike or ATV?

Compatibility depends on throat diameter, bolt spacing and air filter mount size. This unit has a 19mm engine opening and 48mm bolt hole spacing, with a 35mm air filter mount—match those measurements to your OEM carb to verify fit.

• Engine opening O.D.: 19mm
• Bolt hole spacing: 48mm
• Air filter mount diameter: 35mm (35mm air filter included)
• Commonly used on Chinese 50/70/90/100/110/125cc ATVs, dirt bikes and go-karts

How easy is the installation and what’s included?

Installation is straightforward for anyone with basic mechanical skills and common tools. The kit includes the parts usually replaced alongside a carb—this reduces trips to parts stores and speeds up the swap.

• 1 × PZ19 carburetor (assembled)
• 1 × 35mm air filter and 1 × gas filter
• 2 × mounting screws, gasket and O-ring
• Check photos and compare to your stock unit before starting

What performance or maintenance differences should I expect?

Replacing an old or clogged carburetor can restore steady idling, throttle response and easier starting compared with a fouled original. This replacement is a hardware swap—not a tuning guarantee—so final performance depends on correct jetting, intake seals and engine condition.

• Restores proper fuel/air delivery when the old carb is worn or clogged
• Included air filter helps keep intake debris out of the carb
• May require minor jetting adjustments for altitude or fuel differences
• Ensure intake and gasket seals are tight to prevent vacuum leaks

How should I verify it before buying and during installation?

Measure your current carb and inspect mounting points, then compare to the product images. While installing, double-check gaskets, hose clamps and fuel filter orientation to avoid leaks and vacuum issues.

• Confirm 19mm throat and 48mm bolt spacing on your existing carb
• Ensure the air filter mount matches the 35mm included filter
• Compare the kit photos to your stock unit for identical appearance
• Tighten clamps and test for leaks before first ride

Who this is for: This MOTOALL PZ19 carburetor kit is aimed at riders and mechanics who need a practical replacement for small-displacement Chinese ATVs, dirt bikes and go-karts.
