AUTOKAY Carburetor for 47-49cc 2-Stroke Pocket Bikes — CA14/MTA1-MTA2 Fit with Air Filter & Gaskets

The AUTOKAY carburetor is a direct-fit replacement carb for 47–49cc 2-stroke pocket bikes and scooters, including COOLSTER QG50 DB49A models with MTA1/MTA2 CA14 fittings.

If your mini dirt bike or pocket scooter is running poorly, stalling, or struggling to accelerate, a worn or clogged carburetor is often the cause. This AUTOKAY unit is built as a straightforward swap for many 47cc–49cc two-stroke engines. It ships with the common installation parts you’ll need—air filter, gasket, fuel lines, and a fuel filter—so you can replace the carb and get back to riding with minimal extra parts or trips to the store.

Will this carburetor fit my bike model?

This AUTOKAY carburetor is designed to fit a wide range of small two-stroke engines. It is compatible with 47cc and 49cc mini pocket bikes and many mini dirt bikes, specifically noted for COOLSTER QG50 and DB49A series that use MTA1/MTA2 or CA14 style connections.

• Compatible engine sizes: 47cc–49cc two-stroke
• Noted models: COOLSTER QG50, DB49A
• Carburetor types: MTA1, MTA2, CA14 style fittings
• Recommended when original carb shows clogs, leaks, or poor throttle response

How easy is installation and what’s included?

Installation is intended to be direct and user-friendly when your bike uses the same mounting and fuel connections. The package includes basic parts commonly needed for a swap so you won’t need additional small components in most cases.

• Included: 1 carburetor, 1 air filter, 1 gasket, 2 fuel lines, 1 fuel filter
• Basic tools required: screwdriver, pliers, wrench set
• Typical time: 30–90 minutes depending on experience and access
• Check: match mounting flange, throttle cable, and fuel nipple positions before installation

What performance differences should I expect after replacing the carb?

A fresh carburetor can restore consistent fuel flow and throttle response that degrade over time. Expect smoother idling, more reliable acceleration, and fewer stalls if the original unit was fouled or leaking.

• Improved idle stability and quicker throttle response
• Reduced sputtering and stalling under load
• Better fuel delivery when jets and passages are clean and correctly tuned
• May require minor tuning of idle and mixture screws for optimal performance

Who is this for? This AUTOKAY carburetor kit is aimed at owners and home mechanics of small two-stroke machines—mini dirt bikes, pocket bikes, and scooters—who need a reliable replacement carb that includes the basic install parts. It's a practical choice for riders with COOLSTER QG50 or DB49A models or anyone with an engine using MTA1, MTA2, or CA14-style carburetor fittings. If you perform basic maintenance and can match mounting points and throttle connections, this kit will let you replace a faulty carburetor quickly and return your bike to usable condition without unnecessary extras.
