Dummys guide to carburated engines

Chrysler Tech is Carter oriented.
The fundamentals are the same so its not a big deal for introduction to how they work.
Carter used a second bleed in the idle circuit they called an 'economizer'. Another difference is the use of a balance tube insead of a vent. These are getting into a level of detail well beyond basics.

The Imperial club has a some Carter manuals on-line.
At some point you will need to open one up. When you see the parts and follow those instructions, there will be no explanations about what they do. You put the two together; the parts you're holding and what you read about how they work.
Eventually you'll make changes, maybe just small ones like adjust idle mix, and observe what happens.
