My next project on my 67 bird is dealing with the Rochester Quadrajet 4bbl carb. I plan to rebuild it myself, but have never done it and I know I am missing a spring or 2. Because the 'air valve' for the front 2 barrels is flapping in the wind. Also, there are some plugs on hoses/ports that I am not sure should be there. There are a few books out on it, but in reading reviews, they all have some faults. Anyone have a favorite book, method, or some pictures of their carb they can send me? Also, I know this will be a meticulous job, but how reasonable is it to do, and how hard is it to tune the carb? So really any helpful info you have on this would be great. I am just getting into the whole rebuild, so my experience is limited.
