Hello guys, I have a 125 he Pegasus Corona Sport that starts badly. If he starts the rear wheel turns wildly with it. As if I give a lot of gas. The rope pull from the carburetor is loose, I can only keep the scooter running when the rear wheel hangs in the air, and when it stands on the stand. When I go on the brake the engine dies immediately off.Have let it on and fetched from the stand there he rode immediately like a horse and then drove a few meters. The starter has to fight that the engine is spinning. Although the battery is charged. And after a few attempts the starter only clicks.What could this be about? Variomatik carburettor has someone had an idea or already? I am open to suggestions for solutions. Thank you already in advance for the hints. Greeting Werner
