My Wuyang Honda Joy 100C often opens and closes automatically, and it is easy to close when it is opened slowly. I asked someone to repair the car and said it was engine oil, so I changed the engine oil. It is easy to stall at low speed. First, check whether the idle speed is too low. If the idle speed is not low, you can clean the air filter and carburetor. The carburetor shuts down easily. In addition, check whether the valve clearance is too small, whether the spark plug is broken, and whether the intake pipe and oil suction pipe of the fuel tank switch are aging and leaking oil.
