Kymco Agility City 50 4t bugs not to start

I guess I lost the thread on the scooter, maybe someone can give me a hint. The scooter left me standing again and again. It suddenly ran again or not. The last time I had cleaned up the carburetor in the ultrasound, everything together and Zack, he ran. Test drive, back to the yard and he went out. Since then he doesn’t make a sound anymore. He had for my taste a weak compression, so valve lid down, Übersc The piston shirt is heavily sanded, so new running set on it. Renewed: cylinder and piston ignition coil alternator and pickup spark plug suction tract complete carburetor with all fuel lines and vacuum hoses Simmerring KW Variator side He just doesn’t want. Nothing, not even a cougher. Also not with start pilot. Ignition spark as spark remains dry, it smells minimally of Benz in…. Carburettor has fuel insulator on the carburettor is also really around) Engine has compression, engine is standing (I’m 99.5% sure) right, maybe who has a tip for me?
