Idling problem of carburetor of Ling Ying 1 10 curved beam motorcycle.

Check whether the mixing screw has moved. Generally speaking, there are two adjusting screws on the carburetor, one is the idle screw with spring, and the other is the mixed screw, which are close to each other. After finding the mixture screw, screw it clockwise to the end, then quit one and a half turns, start the engine to warm up for a while, and then adjust the idle speed to stabilize before commissioning. If this still doesn't work, it's necessary to go to after-sales inspection and adjustment. In addition, the air door should be pulled when the cold car starts, and the warm-up engine should be sent back to the air door handle after it works smoothly, otherwise it will be easy to stall without refueling.
