Where is the choke on a scooter?

The choke on a scooter is automatic, which is an electronically controlled enrichment valve installed on the carburetor. It is a black plastic component with wires next to the carburetor. This 'choke' is controlled by temperature and current, requiring no manual operation. When the engine is turned off, the power supply to the 'choke' stops, and after a while, it automatically opens the enrichment nozzle. Upon restarting, the carburetor will automatically provide a richer air-fuel mixture, equivalent to pulling the choke. Once the engine starts running, it begins supplying power to the 'choke,' causing it to close quickly. At this point, the carburetor starts providing a normal-concentration air-fuel mixture. The function of the choke: Also known as the air choke, it operates on two principles. One is to reduce air flow during cold starts, and the other is to increase fuel flow. Both methods ultimately provide the engine with a richer air-fuel mixture, which is beneficial for easier engine starts in cold conditions. The choke automatically opens when the engine is cold and closes once the engine warms up. Motorcycles control the air intake to reduce the air ratio. Therefore, if you are not in a hurry to ride, it is advisable to let the motorcycle idle for 1-2 minutes to allow better control of the air intake.
When I first started riding scooters, I often had trouble starting them in cold weather, and not knowing where the choke was could be really annoying. Most scooters have the choke located near the left handlebar—it's a small black or metal lever or knob. Pulling it up restricts airflow, making the fuel mixture richer, which is ideal for cold starts. You must push it back immediately after starting, or the scooter might sputter, consume more fuel, or stall unexpectedly. If you can't find it, try checking the scooter's manual—it usually has diagrams—or look directly at the carburetor connection. Some older models hide it under the seat. From my experience, using the choke in winter saves a lot of time, but don’t force it—if it gets stuck, you’ll need a mechanic. Overall, it’s easy to locate and simple to use; the key is forming the habit of turning it on when needed and off afterward.
