A complete AUTOKAY replacement carburetor kit designed to restore smooth throttle response and reliable fuel delivery on 47cc–49cc 2‑stroke mini pocket bikes like the COOLSTER QG50 DB49A.

This OEM‑style carburetor bundle from AUTOKAY includes all the basic parts needed to swap out a worn or damaged carburetor and get a small dirt bike, pocket bike, or scooter running again. The kit comes with the carb body, a compact foam air filter, gasket, fuel lines and an inline fuel filter so you can install it quickly and avoid scavenging parts from several sources. It’s engineered for compatibility with many 47cc–49cc 2‑stroke engines and matches common mounting and fuel inlet configurations found on COOLSTER QG50 DB49A style bikes.

Will this carburetor fit my 47cc or 49cc pocket bike?

Yes — the AUTOKAY unit is made to be compatible with most 47cc and 49cc mini dirt bikes and pocket bikes that use a similar carburetor flange and fuel inlet layout. Check the flange bolt spacing and fuel line diameter on your bike to confirm fitment before ordering.

• Designed for 47cc–49cc 2‑stroke mini engines
• Matches common bolt pattern used on COOLSTER QG50 DB49A models
• Includes fuel lines and gasket to simplify installation

How simple is installation for a DIY mechanic?

Installation is straightforward with basic hand tools and a few minutes of mechanical experience. The kit contains the main components you’ll need, so you won’t have to source small parts separately; however, you should clean mounting surfaces and adjust idle/air screws after fitting.

• Includes carburetor, air filter, gasket, fuel lines, and inline fuel filter
• Requires common hand tools: screwdriver, wrench, pliers
• Recommended to tune idle and mixture after installation

What performance changes should I expect after replacing the carburetor?

Replacing a clogged or leaky carburetor typically improves throttle response, smoother idling, and easier starting. This AUTOKAY kit restores consistent fuel delivery but tuning may be required to match your exhaust, airbox, or altitude for optimal running.

• Better throttle response versus a fouled stock carb
• Smoother idle and more predictable acceleration
• Tuning adjustments may be necessary for peak performance

What comes in the package and what should I inspect first?

The package includes one carburetor, one foam-style air filter, one mounting gasket, two lengths of fuel line, and one small inline fuel filter. On arrival, verify the gasket and fuel lines are intact, and inspect the carburetor flange, throttle shaft, and choke linkage for smooth operation.

• 1 × AUTOKAY carburetor (main body)
• 1 × foam air filter, 1 × carburetor gasket
• 2 × fuel lines and 1 × inline fuel filter included

Who this is for: If you own a COOLSTER QG50 DB49A style pocket bike, a 47cc–49cc mini dirt bike, or any similar small two‑stroke machine and you’re facing hard starting, poor idle, or fuel leaks, this AUTOKAY replacement kit provides a cost‑effective way to restore reliable fueling. It’s ideal for home mechanics, hobby riders, and repair shops that need a ready‑to‑install carburetor with the basic accessories included. Note: always compare physical dimensions and mounting details to your original carburetor before purchase to ensure fitment.
