“… a considerable percentage of the fuel leaving the chamber unburned.”

I bought a used ‘79 RX-7 in 1990 with about 130,000 miles on it. When it started up, it emitted a large cloud of white vapor.

When I turned it off, usually at the gas station, that un burned fuel ignited in the exhaust line. It was not unlike a gunshot.

I’d like to apologize to those whose hearts I stopped.

Oh yeah! Give a throttle blip during shutdown and you could cause a huge back-fire, sometimes occurring after you already exited the car! Always a crowd pleaser.
