Hello I have been standing a Keeway Ry8 for longer because I wanted to make fit for the summer again. Last stand was that he drove super until he went out all at once during the ride. Presumably at that time was on piston eater(22,000km) . I have now installed a new cylinder + piston, new membrane, new E choke, new petrol tap with filter etc gasser cleaned in the ultrasonic bath. At the disassembly I saw that the old piston had no feeder at all but since I had disassembled it anyway ka So the mistake at that time was something else. So now to the mistake: I built everything together and drove a lap. Roller did not jump in for a long time. Only when I turned the mixing screw almost completely in. Then it ran really great but after 5km it went out. Again gassed removed and saw that the intake snoring from the air filter has a crack. Now the mysterious, With broken hose= he jumps badly, drives 5km well then goes out. With new sh lauch = jumps super but doesn’t take any gas and goes almost out of gas Is that a sign of too little fuel or too much? Almost with false air he actually drives better (just not long)
