can somebody explain something to me.
 

ive been talking to some people who SWEAR that its possible for an engine to somehow rotate in the opposite direction... as in after a car stalls, the engine fires from compression and heat, diesels, without the spark, then somehow rotates in the opposite direction... i didnt think this was possible at all, but for whatever reason the argument just wont die... am i just wrong?

I've had a worn out 327 do it, shut it off, it diesel and rotate backwards and weeez, whats the problem???
