Pete,
That 3rd port on the bottom of my 34ICH is blocked by the gasket as well. I just rebuilt mine too, so I remember thinking "hmmm" as I reassembled it. Mine chokes and sputters quite a bit off throttle, and I am pulling my hair out over what's wrong. I think I may have a vacuum leak, but I haven't been able to find it. Mine will back fire and miss when I'm going down hill off throttle. If I rev it a bit as I come off the gas, it seems to behave a bit better.
Best of luck.
