RedCap PZ22 22mm Carburetor for 110–125cc Pit Bikes and ATVs — 38mm Filter Flange, Cable Choke

This complete carburetor unit offers tunable idle and air-fuel adjustments, a removable float bowl for easier maintenance, and a 38mm filter mounting face to accept a wide range of intake filters. Built as a direct-fit option for many popular small-displacement engines, it’s intended to replace worn PZ19-type carbs or provide a performance-minded upgrade when matched correctly to your machine.

How will this carburetor improve starting and idle behavior?

Swapping to the RedCap PZ22 can stabilize idle and make cold starts more predictable thanks to its cable choke and adjustable idle screw. The enlarged 22mm bore compared with smaller stock carbs often improves throttle response at lower RPMs while allowing precise mixture tuning.

• 22mm venturi for improved low-end throttle response
• Cable-operated choke for consistent cold starts
• External idle and air-fuel mixture screws for on-bike tuning
• Removable float bowl for quicker access during servicing

Will this fit my SSR, Apollo, Taotao or similar 110cc–125cc engine?

The RedCap PZ22 is made to match many Chinese-made 110–125cc engines, but fitment depends on manifold spacing and mount style. Measure your current carb: bolt-to-bolt dimensions, spigot diameter, and choke type to confirm compatibility before buying.

• Carb bore: 22mm — confirm against your OEM unit
• Filter flange: 38mm for common aftermarket filters
• Mount type: spigot with 48mm center-to-center bolt spacing
• Choke: cable-operated; verify your throttle/choke cable routing

What installation and tuning steps should I expect after purchase?

Install requires removing the old carb, matching the spigot and bolt spacing, and reconnecting the throttle and choke cables. After basic installation, warm up the engine and fine-tune idle and mixture screws to achieve smooth throttle response and proper running across the rpm range.

• Compare bolt spacing and spigot diameter to your original carb
• Attach 38mm air filter or adapter as needed
• Set initial mixture and idle, then refine during test ride
• Inspect for vacuum leaks and secure all clamps

What parts and machines is this carburetor compatible with?

This unit is commonly used on a wide variety of Chinese-made pit bikes, dirt bikes, and ATVs. It’s a popular replacement for models from SSR, Sunl, Roketa, Taotao, Coolster, ThumpStar and other similar brands, but always verify visually against your original part.

• Intended for many 110cc–125cc Chinese engine platforms
• Commonly paired with pit bikes, small dirt bikes, and quad ATVs
• Often used as an upgrade from PZ19-style carburetors
• Not guaranteed for every model — compare measurements first

Who this is for: mechanics, hobbyists, and riders who maintain or modify small-displacement Chinese pit bikes and ATVs and need a reliable replacement or performance-oriented upgrade. If you want easier maintenance access, a cable choke for consistent starting, and a 38mm filter mounting face to broaden aftermarket filter choices, the RedCap PZ22 is engineered to be a practical, serviceable option. If you’re unsure about fitment, capture a photo and measurements of your current carburetor and contact the seller for assistance before ordering.
