Mooooin together. I recently got an Olever Sport for free. The completely disassembled (I don’t know anything about) with a cousin, oils changed, carburettor completely disassembled and cleaned, a defective oil hose renewed and nu was test drive. It is loud as if there was something in the Vario area. and after about 5 km it simply turned out at the traffic light. When starting it only makes CLICK…… nothing goes. Had already the problem that the piston was fixed and if you had moved it manually he went again. Well…. Probably hot running wa? As I said I have no idea at all but wants to get him started himself…. What can it be? Thought only on piston rings that might have burst. NEGATIV. When we had removed the oil pump in the engine block no liquid. Is that right?
