These days a lot of guys are restoring cars, not with crate engines and aftermarket Holley or Edelbrock carbs, but with antique drive trains using old-school fuel systems. Rochester made carburetors from 1932 into the 1990's for many of the greatest cars - General Motors products like 5-6-7 Chevies as well as Studebaker, Packard and others. Some of the most sought-after Rochester carbs are the Tri Power carburetors that used three Rochester Two-Jet (2G) carbs on the Oldsmobile J-2 setup, 348 Chevy, Cadillacs, Pontiacs and the '66 Olds 400.

To make restoring these great old cars easier, we've scanned in the entire Rochester carburetor service manual covering the years 1932-1980 and we're presenting it here - for free.

The manual is in two formats - regular html pages with jpeg images of the scanned pages - and pdf files.

You will also find detailed service manuals for specific Rochester carburetor types in downloadable ebook format.

Some additional parts were cross references of carb numbers by model type, lists of kits and parts and service bulletins. We have tried to preserve as much of that information as possible here.
