Product Overview
Upgrade or replace a worn, clogged, leaking, or poorly performing carburetor with this 19mm performance carburetor and 58mm air filter kit, designed for select 2-stroke 49cc, 50cc, 60cc, 66cc, 70cc, and 80cc motorized bicycles, pocket bikes, scooters, quads, mini ATVs, and small-engine applications.
The carburetor controls the air and fuel mixture entering the engine. A properly matched carburetor can help improve starting, idle stability, throttle response, fuel delivery, and acceleration. If your 2-stroke motorized bike or pocket bike has hard starting, rough idle, hesitation, poor throttle response, weak acceleration, or unstable running, replacing the carburetor may help restore smoother engine performance.
This carburetor features a 19mm manifold intake bore diameter and a 58mm air filter side mounting diameter. It is commonly used as a performance replacement or upgrade carburetor, so fitment must be confirmed by intake size, air filter side, throttle cable setup, choke style, fuel inlet position, jet size, and available installation space before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This carburetor may fit select 2-stroke motorized bicycles, pocket bikes, scooters, quads, and mini ATVs using 37cc–80cc engines when the original carburetor size and setup match. Main applications include 49cc, 50cc, 60cc, 66cc, 70cc, and 80cc 2-stroke engines. Please compare your original carburetor’s intake bore, air filter side diameter, throttle cable setup, choke style, fuel inlet position, and overall shape before ordering.
Do I need to match the OEM part number?
No confirmed OEM part number is provided for this carburetor. For universal-style 2-stroke carburetors, physical fitment is more important than model name alone. Please confirm the 19mm manifold intake bore diameter, 58mm air filter side mounting diameter, 6mm jet style, throttle cable connection, choke layout, fuel inlet position, and available installation space.
What models or situations does this part not fit?
This part does not fit motorized bicycles, pocket bikes, scooters, ATVs, quads, or small engines that use a different carburetor size, different intake manifold, different air filter connection, different throttle cable end, different choke design, fuel injection system, or limited installation clearance. It is also not a replacement for the intake manifold, reed valve, fuel petcock, fuel pump, throttle cable, fuel line, or complete engine kit.
What should I check before ordering?
Before ordering, please check your vehicle’s engine size, engine type, original carburetor style, manifold intake bore diameter, air filter side mounting diameter, throttle cable connection, choke setup, fuel inlet position, jet style, and overall shape. For best fitment, compare the product photos and specifications with your original carburetor before purchase.
The sun was working excellent but I happened to break the clipart for the clamps so it's out but it was excellent I just kind of accidentally snapped it but I will get another one definitely good for the little 49cc .
