HP Books has a really good book on Q-Jets that detail every adjustment and how to make them scream. Even for the basic rebuild it is very helpful.

I would recommend also going to You Tube and typing in QuadraJet Rebuild or something close to that.

mmiddle summed it up very nicely. But on Q-Jets you have to pay attention to details. Once you get one or two under your belt the rebuilds go smoothly.

Good luck.
