Perhaps you can explain again what you did when you're sober... 
I don't have a clue what you're talking about.

I think is what he is trying to say is:
He plugged all the vacuum ports on the carb as well as the manifold. The distributor ran without any vacuum advance hooked up.
Yes, it will run. Just not very well. Perhaps unplugging all the vacuum accessories is the influence of alchohol showing through.

That setup won't cost you power, but it will cost you fuel economy.

You don't run vacuum "to" the carb, the vacuum ports on the carb and intake are sources of vacuum.
