Hello scooter screwdriver, I have a Piaggio ZIP 2t, year 96, 50 km/h. The scooter starts and runs for a short time at the stand. Then it goes out, gas-giving doesn’t help either. After that it doesn’t start again, only the next day. The spark plug is always wet after the start attempt. The scooter is still original without freezing. Have already checked or changed following things: -Zündkerze has completely cleaned sparks-gasifier – Weber 12 OM and blown through -Replacement carburettor umge I wanted to check the compression, I ordered a corresponding device. Next I would like to check the suction socket, optically it has no cracks or the membrane change (already ordered). Could it be that the Simmerrings are leaking on the crankcase or the piston rings are already worn out. For your support I would like to thank you in advance. From Monday to 3 weeks on holiday. I don’t have Wi-Fi yet. Charly
