Ive bought a stunt (piaggio fastrider frame, gilera runner lc 50cc engine). I drove it for 20min and I was going uphill it all semed fine but then the engine buged and made sound like it has too much air.I left it for 5sec and then i drove up. At the top i turned off the engine and rolled down hill. But then it didnt want to start back up. There was gas, the cooling worked,I fell that the piston is moving nice there was same compresion but it just didnt start. Any ideas why?
