often, there is excessive carbon on head/pistons, may act like "glow plug"
and stay hot and also raises compression ratio (since it reduces effective
combustion chamber size), thereby raising the temperature of the fuel/air
charge enough at the end of compression stroke (remember the ideal gas
equation, Charles' law, etc.) to ignite without spark, just like a real
diesel- a clue is cylinder pressures that are too high (probably *much*
higher than 160-170)- you may have to pull the head, please keep us
informed
