If I were cleaning it out, I'd use Carbureator Cleaner. That shite takes ANYTHING OFF. Trust me. I used it on my valve cover when I was cleaning it to paint it. Plus it evaporates (mostly...I'd still rinse it once or twice). As for the gasket, I'm thinking that they're talking about the older style gaskets (don't quote me on it though). Buy Fel-Pro. Most of their stuff doesn't require any type of adhesive to be applied.
