One of the problems I was having was trying to figure it out in the comfort of my heated home. Someone mentioned the choke needs to be "outside" cold for it to work. I moved my carb out to my garage and and played with the linkage in the morning. It made better sense then. I also called Edelbrock tech support for an unrelated question, and the guy totally set me straight on my application and what I need to do. 300 bucks later, I have a new dual plane intake (and more) on the way to replace the existing single plane. I can't wait to see and hear it all put together.
