?sorta backwards run

I think what gets lost in people saying their engine ran backward, is that when they shut down,just before the engine stops,a hot piece of carbon or whatever will ignite left over fuel . vapor in a cylinder that has a piston not at TDC,thus driving it back down,thus turning the engine backwards,BUT only by
momentum,just a "kick" in reverse rotation.Not actually running.I have saw engines do this,have saw them do it from a bad out of time problem and they break the starter cause it was engaged when it "kicked" backward.Not being a smart a$$, seriously asking, what is going on when we pull our lawn mower starter rope,and it rips from our hand? beside the cursing that is..If it was "kicking" in normal rotation direction,wouldnt the ratchet in it release and not rip out fingers off just like it does when it does start? Why was so many people injured back years ago with hand crank cars? a backards "kick?"
I agree they cant run backwards,but the "kick" gets translated into "run"
I may be wrong,i have been known to be wrong,wife says i am always wrong,thats what is so right about me ! idea's NE1??

I used to know a guy who said if you flipped your cars rear end upside down,you would have 3 or 4 reverse speeds(depending on tranny) and 1 forward.
And another friend was tedlling me how in his automatic tranny car,he would go down the highway at speed,put it in reverse,and spin the tires off backwards while the car was still moving forward.
wonder how many people know most auto trannys wont even go into gear if the engine is near max rev's?
