Then maybe you can explain why that matters.  Obviously you need a spark in
that kind of engine to start combustion.  I've heard people talk of stronge=
r
sparks being better, but nobody has ever explained exactly why.  What is th=
e
advantage of a stronger spark past reliably starting combustion?  Once some
combustion starts, why can't it be considered the "spark" for further
combustion until it runs to completion?  No matter how strong the spark,
wouldn't it still only ignite a small portion of the mixture in the
cylinder, which means it's relying on the combustion chain reaction for mos=
t
of the burning regardless of how strong the spark is?
