Speedfight 1 LC still problems.

Hello dear community. I still have problems at my Speedfight 1 LC. What I have done so far Is petrol tap renewed, due to defective (lock no longer. Carburettor Changed (completely waited) Carburettor needle brought to center position was set at the bottom Carburettor set Mixer screw 2 revolutions Out And air 1 1/2 revolutions out Everything sprayed with start pilot No speed Change noticed Error picture found: Roller starts with e starter or K Ichstarter direkt, If you give gas the engine takes that on! At the latest at full throttle the scooter goes off while turning up. Now there are 2 ways for me fault diagnosis and repair workshop! Where the hourly wage is indeed expensive in the between 85 and 90 Euro incl. VAT I as customer service technician in the SHK craft takes my boss about 75 Euro incl. VAT or I try it Next, is worth a flammable gun? Ever compression tester would I order anyway What a way would you take And can I keep bugging you with the problem of scooters?
