I'm like a lot of you shade tree restorers out there; not much I won't tackle, but certain things are a bit too scary to try. Rebuilding the carburetor was one of those things.I bought this book, as well as the Roe QJet book just to cover my bases. If you want to try a rebuild, I'd recommend you have both books. There are some minor gaps in this book that Roe will cover, and vice versa (for example, Haynes recommends Loc-Tite for throttle body screws, which can work loose and fall in the engine, Roe ignored this potential issue). The Haynes book does a better job covering other Rochester carbs, including a side by side guide for rebuilding the DualJet and QuadraJet, though the side by side instructions can be confusing at times.I was able to get through a QJet rebuild in a very measured, cautious six hours. The carb worked flawlessly the first time, thanks to this book.
