I have a 2001 Honda XR80r that I'm getting together for my nephew that has been nothing but problems. I've heard it start, but run only briefly and now it wont even pop. I have a new ignition system, spark plug, carb, tank, and it has a blue spark. I have no clue what's causing it. I thought it might be the magnet of the flywheel because it was chipped and not too magnetic. Replaced it with another and still nothing. It kicks over OK and I heard it run before and it sounded decent, just shut off after a while which prompted me to get a new carb. I had to kick it like crazy to get it spinning so it would start then, which is why I thought it might be the flywheel magnet. This is beyond frustrating and I'm beginning to think the little bastard is cursed or something. Might take it down to the stealership for diagnosis because I'm at my wits end. Is there anything I'm missing that would keep it from running? The carb is new, I timed it out and the valves are set OK. Any help is appreciated.
