I'm saying that most failed engine starts from iced-over plugs occur
after a few combustion cycles due to the water vapor liberated through
combustion being combined with an already high ambient relative
humidity. I'm saying that the spark plays no role in concentrating
the ice between the plug's electrodes. To be convinced of such a
spark induced ice concentrating phenomena, I would have to see either
an authoritative paper detailing the physical mechanism involved or a
controlled experiment with such results. You may be correct, Bob, but
the scientist and engineer in me needs more before I buy it. If I'm
proved wrong, I'll hoist a frosted mug to you.

Which came first...
the chicken or the egg?

Matters not when you and your spark plugs are frostbit
on some lonely mountain top and your engine won't start....
and your battery is running down. Better have a plug
wrench or know how to prevent spark plug frosting
in the first place. Scientific explanations be damned.
