Definitely check out the tors system, there are three connectors you can unplug to bypass it and see if that was the problem. They connectors all look very similar. One is the set of wires coming from the thumb throttle, one is coming from the carb, and last set is on the little black box under the hood, top right one I believe, it will have a similar connector as the other two you need to disconnect. Mine had same problem, thats one reason I got it so cheap, and the TORS system was the culprit, took my 5 min to get it running, if that long. Check that first, also, when you kick start and your light switch is on, do the lights light up a little? (kick it hard)
