Dar,
That other thread talks about a flooded 2 stroke kicking back, this thread, unless I'm very much wrong, is talking about a 4 stroke which doesn't usually have a problem with fuel filling the crankcase and flooding up into the combustion chamber. My comments here were strictly limited to your statement in this thread that a rich mixture can cause detonation by raising the compression. A rich engine is an entirely different thing to a flooded engine.
