My friend has a light-blue 93 Tomos Sprint, and it won't start. He has a new spark plug and I don't know what could be the problem. I was guessing it needed a new piston kit, or it's just flooded. It doesn't have side panels, and he left it in the rain last night. We've been tryin to get it started half of the day.If you need more detail on what it looks like, there's a pic of it posted on this web site. Any on all help would be greatly appreciated.
