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.

There is a good write up on super chevy.com.
