Hello scooter community, after many futile attempts to get a used bought scooter (ATU Race GT50) to run properly, now the ideas run out and I hope that someone from the forum still has a good tip in stock. Therefore: Hello for the first time! 🙂 The problem is this: I start the scooter, drive with it quite normally a few kilometers – he does not cause problems, takes on gas quite normally, does not stutter. Upon arrival at the finish I turn off the engine, do what I z The scooter usually starts without problems, starts without problems, but after a few hundred meters it suddenly goes out (the drive continues and the engine is rolling off). Then it is supposed to wait (about 3-5 minutes). After this time it jumps again (no chance before that) and so it then drives again a few dozen meters until it stops and the fun starts from the beginning. My previous tests / experience The gas filter looked relatively empty. So I took an extra hose and removed the vacuum hose from the gas tap, put the extra hose on it and pulled it on it until I saw that there was a lot of petrol in the petrol filter. Scooter dropped, after a few dozen meters stopped again – so it probably wasn’t due to the lack of fuel. I also looked at the gas filter. If there is spark during the acute phase – yes, it is. So I just can’t explain why the scooter always runs out during the ride after a ride and then pause. It seems nothing to be missing. I have done the following: Electrical: – new spark plug cable – new spark plug (by NGK, same as in the service manual) – new CDI (DC / throttled) Other: – tank completely emptied, cleaned – tank tap tested – petrol filter exchanged – air filter exchanged (ge Gen Original) – Carburettor disassembled and cleaned – Carburettor set clean with warm engine – Battery changed Has anyone changed an idea what to do/check now? Thank you in advance and greetings!
