m trying to adjust the idle on my px125 (bog standard)as when Im sitting at idle the exhaust is continually popping (misfire?) and the scooter vibrates, instead of giving a smooth steady idle. It seems to run roughly at low speed with vibration, but fine at high speed. I have the idle speed screw 1.5 turns out and the idle mixture screw at 2.5 turns out. Any ideas?
