So uh... why does nobody post what fixed the problem? This problem is all over forums, but I have only found one person posting the solution - which was the rectifier, but I would like more corroboration on that. It should run without the rectifier as long as the battery has a good charge ya? I'm having the same issue. I tried push starting it with another wheeler to see if the starter itself was drawing to much power or if the start button was grounding the spark out somehow but that didn't work. Let me know what fixed yours please. Cheers.
