Re: what are pionts
If you get the flywheel off and can examine them, you should look for pitting on the contacts. If excessive, I'd replace them. They should be smooth and not nessesarily shiny, but heavy pitting is not good. They will not generate the spark nessesary to fire the plugs to full potential. Sometimes if they are slightly pitted, they can be lightly sanded down using emery cloth and re-gapped and used again. An old trick to see if they are working at all, is to turn the motor over so that the points are open and arc them with a screwdriver with the ignition key on and see if they spark. If so, at least you know you know you are getting spark that far. If it's been a while, I'd replace them anyway, as long as you have the flywhell off. Replace the condensor, too.
