Aprilia SR 50 LC no longer wants to…

Moin Moin… I’m pretty desperate a few days ago, because the scooter of an acquaintance unfortunately doesn’t want to start at all and I’m now at a loss. I’m dealing with an Aprilia SR 50 LC, which just went out a year ago during the ride and never sprang up again. I looked at the whole thing and went to troubleshooting, but now I’m at the point where I don’t know any more. He has compression, an ignition spark, gets fuel and the exhaust is also free. Even with the start pilot it does not ignite. My first thought was the ignition coil, because it was sparking at first quite weak, but even with a newly installed coil and stronger ignition spark it became nothing… Would be very grateful if anyone here still has further ideas about what the whole thing can be about. I have the feeling that it is related to the ignition / ignition sparks, because it does not even react to the start pilot, but the spark is just visible at the frame, find that i I thought that he was drunk several times, but then I could rule it out, after I “emptyed” him a few times… LG Daniel
