Please refer to the '''''Books/ Guides/ Websites /Multimedia''''' section immediately below for helpful materials. =====Books/guides/websites/multimedia===== :[http://www.cliffshighperformance.com/buy_book_all.html '''''How to Rebuild and Modify Rochester Quadrajet Carburetors'''''] by Cliff Ruggles is a frequent recommendation by the members of [http://www.hotrodders.com Hotrodders] forum.

Newer, improved videos may be available by other authors as well so be sure to check for current material. =====Carburetor identification: Locations and decoding===== :Once it has been determined that your Rochester Quadrajet carburetor requires a rebuild, the first thing to do is to locate the identification number. The identification number will help with ordering the correct parts or a rebuild kit. The number is usually found as a stamping in the body of the carb on the driver side of the carburetor, running vertically up and down. Very early model Q-jets used a round disc attached to the drive side of the carb. These carbs have the less desirable needle and seat assembly and float fulcrum location, so unless the carb is being used on a restored or period correct build, the later carbs- especially those with the adjustable part throttle adjustment or 'APT' located on the airhorn- will be a better choice for a performance application. For decoding the carb number, please see the following article for further information and assistance: '''[[Rochester Quadrajet carburetors: Identification and decoding]]''' [[File:Carburetor_Identification_Number.jpg|thumb|center|750x250px|Location of 1968-up Q-jet carb number. Before this the carb number was stamped into a round disc located on the driver side of the carb, towards the front]]
