I bought this moped about a month ago and it worked like a champ until about a week ago. Right now it will only run for about 2 minutes at a time before it sputters out. My guess would be a new spark plug, but I dont know. I'm over it and just want some of my money back. I know this would be perfect for someone who knows something about these things. I have the registration papers somewhere, and I am in Venice.
