  This I know.  One time in my old 36hp Splittie I  was highballing down the
grade between Las Vegas and Baker, California (Home of the tallest
thermometer in the US..or something like that..)  I don't think I'd ever
taken that bus so fast...about 80, I recall.  All of a
sudden...."BANG!...whaap whaap whaap whaap....."  I think "Oh crap, there
goes the motor, finally" but I see no oil smoke and the motor is still
running ok...I go about 5 miles looking for a side road, and pull off..kneel
down and see....a spark plug, hanging down on it's wire..dangling almost on
the pavement...Screw it back in and continue on..no harm done...
