People will say it is technically impossible, but I think it is wishful

During World War II (really!) I worked on a farm in Concord, Mass.
There was a great steel-wheeled tractor that was started with a hand
crank. One time the tractor backfired while the lad was spinning the
crank, and the engine started running backwards. He jumped aboard and
had a great time wheeling it around the yard, one speed forward and
three in reverse. Blue skies! -- Dan Ford


That was a Diesel engine, correct?


My great uncle Ern was nearly killed by a Model T Ford that he cranked up
and the engine backfired and ran backward. 'Course, that guy was nearly
killed so many times...

A Model T will not run backwards. Even if it did run backwards it would in
no way would put your life in danger.- Hide quoted text -

Running backwards for any length of time given the timing of the
spark. Usually you would expect the spark between 8-15 degress past
TDC (to allow the rod to move out and be ready to push down). if it
ran backwards, each ignition would be working against the engine.
