Haojue series diamond leopard motorcycles can't refuel at low speed and throttle at high speed. What happened?

It is possible that the carburetor is blocked or the mixture is too thin. If the throttle can be equipped with a shock absorber, it is basically a carburetor problem. You can check whether the mixture is too thin first. Generally, the carburetor mixing ratio of Diamond Leopard is to screw the mixture screw to the end and then exit for two or three turns, but not all cars are the same. It is best to adjust according to the condition of the car. If it is a third-class car, you can try adding a thin pad under the accelerator oil needle. Clean the carburetor, check whether the idle metering hole and the main metering hole are blocked, and dredge the spray hole on the carburetor with cleaning agent and compressed air.
