What if Neptune's scooter shuts down and leaks oil during exercise?

If Haojue Neptune scooter leaks gasoline during driving, first check whether the negative pressure fuel tank switch is damaged. If the fuel tank switch is damaged, the oil will flow out from the oil suction pipe, which will cause flooding and flameout, and the gasoline will flow out from the carburetor, air filter and even exhaust pipe. If the fuel pipe of the carburetor or the oil suction pipe of the fuel tank switch is unplugged in the case of flameout, these pipelines will not stop flowing, so the fuel tank switch is broken, so just replace it with a new one and suck the oil again. In addition, check whether there is any problem with the float, float needle and oil drain screw of the carburetor.
