Re: stronger spark, why?

That is a possibility. The points are supposed to open at a certain time as the magnets pass by the coil. It is the time that they open that counts, not the gap. But the gap is related to the time, so it is one method of setting them. The accurate way is with a timing fixture. I’ve made a ton of them, but have turned it all over to club member Richard White. http://www.richardsoutboardtools.com
