I started building a Schwinn Clairmont 80cc bike a few weeks ago. I got the engine set up, but it won't start. Every time I ride it, it gives a little put and then dies, but the throttle doesn't engage and the bike goes nowhere. It's not a real expensive kit, but I'm thinking about investing in a new carbeurator and CDI. If I can I'll get a picture or a video up soon so you can see. But any ideas what the problem might be? Help, I'd really like to get out and ride this bad boy.
