Man, I see a lot of suggestions being floated about but before jumping to conclusions, I suggest you go back to *basics* and check the mating (mounting) surface for flatness FIRST.
If you don't already have a straight-edge, get one and use it to confirm both surfaces (intake manifold AND carburetor) are true. I have one that's about 12" long that I got from my Snap On man many years ago. I'd bet you can probably find a inexpensive one (the Snap On item is NOT cheap) at Harbor Freight or some likewise company.
It's easy using a straight-edge and a flashlight. If you confirm a gap with a light, use a feeler gauge to see how much of a void you have and go from there.
If both surfaces are true and you still get a change in idle quality or speed, it could be a shaft issue or a open vacuum port you might not be able to see.
Good luck,
Phill
