TGB Bullet 50cc scooter gasoline drips at failure VIDEO

Hello dear community, I would need your help with my TGB Bullet. He usually drives like an A, sometimes has only small problems, which can be easily fixed. Now I threw him again after a longer life 3/4 year. After 2 times kicking he reacted immediately and jumped on. After he could slowly keep his stand speed on his own, he started to drip below the carburetor (probably the component will be the carburetor). Only less than the engine ran. and after switching off then more. Unfortunately I have no knowledge of the construction and am grateful for every tip! Thank you! A video shows the dripping part of the carburetor. The picture shows the brass outlet from which the petrol outlet.
