This is why the carburator on the civic is so impressive, of course if you remove any of the 54 vacuum hoses it will stop working correctly and cause horrible engine damage like you are talking about.

This must be something I wasn't made aware of during my time with Honda engines. Do you have a reference for this that I can read?

Still, I imagine that if his carb was working properly to begin with (if his were as you describe), it wouldn't have been dumping fuel after shutting the engine off, so the issue would have been negated altogether.
