sfera 80 just went out!

evening! the following problem: My Sfera NSL 80 just went out of the job on the way back today! Before the 1A ran, had only filled up on the way back, then 7 hours later I wanted to drive home, and after 1 km the car just goes out and doesn’t like to go on! In addition, she now also makes a funny noise when you try to start, about as if you had taken off the air filter completely and then let the engine run (she used to drive Mofa without air filter, dan You know what I mean!?) Is such a deep dull sound! I have to say that the scooter was standing around for 20 months before, but the last 100 km he was running really great! What’s this about? By the way, I took about 5 hours until I had organized a trailer, but I was also allowed to unload 2 cubic meters of bark mulch in a blazing sun…
