I just got a motobecane mobylette from a friends grandfather. He's had it in is shed for years. It used to run, but I don't know when the last time was. I have tried to start it and had no luck. I cleaned the points and checked the spark plug boot with a volt meter and it is putting out power. I put in a brand new spark plug (the reccomended one from the owners manual) and it still doesn't spark. Any suggestions would be great. Thanks!
