Urgent! Feng Chun 150 scooter can't absorb oil after two days.

This is the case with scooters. The engine needs to be started or turned before the fuel tank can come out. If it is difficult to start after removing the carburetor, you can check whether there is slight air leakage due to improper installation of the carburetor, whether the electric control damper is not working well, whether the oil switch and oil suction pipe or oil pump pipe are leaking oil, and if necessary, clean the carburetor again to check whether the oil level and mixing ratio are wrong, whether the valve clearance is too small, and whether the carburetor itself is poor or aging.
