“Instantly fixed my issues with the moped bogging down when opening throttle after it’s warmed up. I cleaned the old carb several times with the same issue but this fixed the issue as soon as I put it on. I was very happy that it came with new intake tube, air filter, multiple fuel filters, vacuum hose, and spark plug. This little kit covered all the bases for runability. Replace the parts that this kit includes and adjust your valves and old mopeds will run like new again and at this price I don’t think I’ll bother with much troubleshooting from now on because time wise this kit pays for itself.”

“The media could not be loaded. I got this to replace a carb with a bad choke on a Wolf RX50 scooter. It shipped fast and had a good price. It was an exact fit and installed in about 1/2 hour. I didn’t have to make any adjustments to the settings. It took a while to get started at first as it takes time to get the carb full of gasoline. Now the scooter starts instantly and runs great.”

Bought this carb and all I did was put my correct size of main jet in it and the needle settings and pilot jet and idle fuel screw is set spot on, starts up and runs flawlessly!

Frequently Asked Questions
Q: What is the most common carburetor size for a 50cc Chinese scooter?
A: The most common carburetor size for 50cc Chinese scooters, particularly those with GY6 engines, is often around 18mm to 19mm intake diameter (like a PD18J or similar). However, it’s always best to verify the exact specifications for your scooter model.
Q: Do I need to make modifications to install a new carburetor?
A: Many aftermarket carburetors are designed as direct replacements and require no modifications. However, if you’re upgrading for performance or have a non-standard setup, minor adjustments to cables or mounting might be necessary. Always check the product description and consider consulting your scooter’s service manual.
Q: How do I know if my scooter’s carburetor needs replacing?
A: Signs that your carburetor might need attention include difficulty starting, rough idling, poor acceleration, stalling, or increased fuel consumption. If you’ve tried cleaning your current carburetor without success, replacement is often the next logical step.
Q: Can I put a larger carburetor on my 50cc scooter?
A: While you can physically fit a larger carburetor, it’s often not beneficial for a stock 50cc engine without other modifications. A carburetor that is too large can lead to poor fuel atomization, loss of low-end torque, and inefficient running. For performance gains, it’s best to stick with sizes designed for your engine displacement or consider other upgrades like a big bore kit first.
Q: What is a GY6 carburetor?
A: A GY6 carburetor is a type of carburetor commonly used in many Chinese-made scooters, mopeds, ATVs, and go-karts, particularly those with 50cc to 150cc 4-stroke engines. They are known for their widespread compatibility and availability of aftermarket parts.
Choosing the right carburetor can breathe new life into your 50cc Chinese scooter, transforming your riding experience. By considering compatibility, performance, and ease of installation, you can select a unit that perfectly suits your needs. Happy riding!
