Could you explain "too much spark" being bad, and what plugs cause this and
why?

I thought that was silly myself. What he was probably experiencing isn't
too
muh spark, but rather the spark being in the wrong place in the combustion
chamber, or the heat range of the plug being wrong.

Contrary to popular belief, heat ranges of plugs don't exactly cross
between manufacturers. I think the rule of thumb was that Japanese
plugs tend to run cold, and American plugs tend to run hot, or some
such.

Obviously, a plug that didn't project the tip into the correct location
into the chamber would cause problems too.

My personal opinion for what it's worth is the only thing worth paying
extra for on a plug is platinum as the plug will last longer. But, that is
almost not noticeable, since modern ignition runs at such high voltage
that it will fire a plug that is carboned, oil soaked, MTBE contaminated,
worn tips, etc. etc. as long as the plug wires and coil is in good shape.

Back in the good old days with point ignition it was more important
to have nice clean plugs with sharp edges on the tips.
