When replacing the carb should a new gasket be used? Will not replacing the gasket result in rough idling due to a possible vacuum leak?

depends
new is always better ,you can make your own gasket out of cardboard or cork ,or simply use a bit of gasket glue permatex -
Spend the $$ and put in a new gasket.
When it comes to the carb...
...better safe than sorry!

Gasket procedure not recomended
Gentlemen I have had good luck replacing gaskets and have not had a leak that I have noticed yet, for what it is worth.
First I am very careful saparating the gasket from the sealing surfaces. Then I wipe the gadsket clean and inspect for rough spots. After drying the gasket with a clean rag I spray both sides liberally with WD-40, set in a pan while wet and let it warm in the sun or a warm oven while keeping the gasket wet with the WD-40. After it has set for a while the gasket seems to swell up a little and deffinately does a reasonable job of resealing. I have done this with my carb-bowl gasket and manifold gaskets many ,many times. This method is good when you are going to be removing&replacing as you are testing new jets or parts.
If you are fixing a problem go for the new gasket.
If you are using a sealer around the carburator assembly don't allow anything to leak out a drip into the carb as it could be diasastrous.
