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.


Are you saying that a Model-T is timed at 8-15 degrees past Top Dead
Center?

I hope so, because that sure is not reality for modern engines.

They have manual spark advance. At start up and full retard you are at TDC
give or take a couple of degrees.
