off the shelf carb info needed.

You have to get oil into the engine somehow. Whether through premix, fittings in the manifold or the carb's float bowls, it doesn't really matter very much.

There is an easy way to supercharge a 12A. Just buy one of Atkins' kits. It's not especially cheap, but then again neither is a turbo. It doesn't end up being all that much more expensive, really, especially if you already have a nice NA exhaust. But you are limited on power.
