But why no spark? I'd change out the points and condenser since it is so
cheap and easy. Then go to the carb. But I don't know why the carb could
stop spark.

Do you have a carb. With an idle air control valve? If so that could
explain the symptoms.

probably done a rebuild, but I decided to replace it.

but no spark. So, I am guessing electrical, so the condenser could be it. I
might say carburetion, but you say no spark.
