May I suggest that what ain't broke, don't fix it.
Back when I was young in the 1950's, we "tuned up" things.
Not so much today, a set of points lasts pretty much the life of the engine,
as does the voltage rectifier/regulator.
Now if you have a problem with something malfunctioning, then one needs to DIGANOISE the problem and replace that part, instead of firing the parts cannon and hoping what ever it hits was the problem as that usually not only gets expensive but adds new problems to the equation, as most "NEW" parts
today are 50% bad built by the lowest bidder supplier!
