Hi Scooter friends, I have a scooter engine here (although a QT6, JSD50QT-13) that didn’t sprung up any more. Carburettor is new, pistons and rings I changed, cylinder looks still good, the rings still fit inside the tolerance (0.4mm gap) in the cylinder. The old rings were already worn out. Now I have put everything back together, oiled everything, new seals in and also the valves checked again. So this fits now. Only I want the now before I a How? Fill fuel into the float chamber with a syringe, the syringe can also be used as a mini-tank. But I have no idea what kind of pin-occupation is: http://i.imgur.com/ZCYZuzs.jpg On the internet, only pin-occupations with a blue loop can be found for the China scooters, but this one has a 2nd on the clutch bell for the throttle in addition to the pickup on the pole. To test this will probably not be important…? l but definitely do not heat the CDI.
