On a carbed car, I drive away as soon as it will idle on it's own, usually a minute or so.

You need to get the fluids moving and heat generated ASAP to minimize wear.
This is what I've been told would damage my engine, but I've been following this practice my entire driving life and have never had an engine blow up or need a re-build. I'm no mechanic so I don't get how running rich can damage the cylinder wall outside of the rings.
