moin, I am at the end with my Latin. My old J5 with suction diesel, 250000km and insane 73hp runs impeccable in idle and full throttle. In local traffic with little gas, he jogs. With the petrol engine I would tap on detonator. At the red traffic light in idle no problems, in the first and second gear also not. In the third or fourth gear it starts. Outside of the place everything is again good. At first it was hardly noticeable, now, after over 1000 km, it is clearly noticeable. And, around it sp There are days when this effect doesn’t occur. And there are days when you think the Womo will stop. But it doesn’t (yet). Unfortunately, the fuel line is opaque, filters and hand pump are new. Wouldn’t air be noticeable in the line at full speed or idle? Does anyone have an idea? Greeting from the North
