Roller does not start after gassing!

Moin people I’m–s again I recently bought a Generic xor 50 used a few days later then bought a new carburettor because the old one on the E-choke the thread of the screw was broken now to my problem the new carburettor was defect of the float hung fixed repair brought also nothing to me ordered a new one but the scooter doesn’t want to jump on. I kicked several times so gasoline runs into the carburettor I have already started pilot in the airfil ter sprayed then he went on very briefly and straight out again What can this be for help please is no scooter expert. Ps: With the new carburettor a connection is more like watching the old as well as the pictures I have maybe done something wrong?
