Hello, My scooter had a false ignition while driving (in cold condition) and went out. Right after that he jumped at the first kick without any problems and started to run normally, but after about 5 minutes he suddenly went out again when starting at a traffic light and did not jump any more since the time. Now he only starts with the start pilot and runs until this is burned. I have already cleaned the carburettor, tested sparks of ignition, tested gasoline and tested the membrane. Can anyone help me?
