Worked on a mini bike once that had a problem of quiting.
I rode it and it quit. I tried to start it and it would not go. I pushed it back to the guys garage and took a look at it and went to start it and low and behold it started right up and ran good. I hopped on it and went for a bit of a tour then it coughed and quit again. There I am again yanking on this cord again. Many years ago so I forget if it had a spark, a weak spark or no spark at all. It was north Manitoba just 75 miles south of the North West Teritories and you had to fly in to get to the remote Indian village. We had no store there where I could just go to and get parts so it was all test, test, try.
I checked the points and they were smaller then specs so I gapped them thinking that the small gap was not the problem but I might as well gap them anyhow.
Could not make that bike miss a beat after that. No matter how hard I rode it.
It was the points that had closed the gap and was making the coil saturation time more. To a point it would overheat the coil and the coil would fail almost like clockwork.

I dont know what open points really do, but I know that points that are too close can take an engine that runs good and shut it down just as if someone turned the fuel off
