Quadrajet tuning

[BADAZ chevy guy]

Are there any videos out there explaining the 'Fine tuning' aspects of a Quadrajet? I've seen a lot of videos on rebuilding, but I can't seam to find anything that goes beyond that. Like how to adjust the power piston for the primary metering rods or how to know if the primary or secondary rods need to be leaner or richer. How to select the right jets etc.
I read posts here (and other forums) about how great Q-Jets are "If they're tuned right", and I agree, but nothing about how to do the actual tuning.
Thanks.

      The problem with video's on the web, unless they are produced or backed by a reputable company, they are made from people who are looking for their 15 minutes of fame.
      Now, do not get me wrong, some people really know there stuff, the 2 I just pulled up on you-tube, not so much, pretty useless.
      I have this book, How to Rebuild and Modify Rochester Quadrajet Carburetors (Paperback) Author:  Cliff Ruggles.  It is pretty informative and has helped me understand carburetors a lot.
      I am no expert mind you, I have a guy for that where I live, but if you really want to learn, get either publication of his book (he has 2) and read away, and then if you can find someone near you who knows about them and have them teach you.
