Moin Moin, I have a problem with my scooter again… He survived the winter and now I wanted to start it after I had recharged the battery before. But he didn’t start, so he googled a bit and followed the tips if he doesn’t want to run again after a long service life: -Cartridge removed and cleaned -Cartridge filter changed -New petrol refilled -Startspray tried He ignites and runs briefly, but only as long as you give him the air filter starting aid spray. it turns up with the spray and then runs “normal”. Can it lie on the spark plug or does it sound more like a bigger engine problem? And is it normal that the petrol filter does not completely fill up with fuel after changing? But it’s not full of fuel in it. Maybe it’s still helpful to mention that it doesn’t always have full power before the winter break. normal he drove so about 50-60 and later on the mountain hardly over 25-30. Thank you!
