Scooter doesn’t start or very bad, Flex Tech Fun 50, it’s starting to piss me off real

Hello is the carburetor sitting on the cylinder or combustion chamber, or what do you call it ? sorry In any case, the room always runs full of gasoline so we don’t start. If you loosen the screws and pull the carburetor up a bit it starts. What can I do, control, renew ? Or knock the whole scooter into the ton. Slowly the muzzle full. Has only run 4000 km. gruss
