Holley secondaries won't open

Thank you to all the replies. I've worked on a lot of carburetors but never on a car so when I'm looking over everything, and don't see the secondaries moving, I thought something was broken.

nm9stheham, you hit the nail on the head. That's exactly what I was looking for. I needed to know how it worked and how to test it, and you cleared it up. I'm going to test it out off the carb, then try the paper clip trick if that checks out ok. I guess it's a stock cam, the guy I bought it from never mentioned anything about putting a cam in. I'm trying to see if a 4 barrel manifold is in the budget. I've seen some of the performers for under 100 on ebay. I don't know if it's worth it if I can't get a cam as well, if it won't make a difference. Maybe I should get a smaller 4 bbl? Or go back to a 2 bbl?
