Re: Tuning Q after a tear-down ordeal...
One thing about those old Q-jets is... the holes where the throttle blade shaft goes through the main body of the carb will get "egged out" over time. Causing vacuum leaks. The only way to fix this is to have the shafts removed, drill the holes oversized and have bushings installed. There are a few machine shops left in the world that still know how to do this.
But you might have to send it to a "carb shop" to have it done. Either Car Craft, or Hot Rod, or one of the bigger name magazines did a tech article on how to do it yourself.
