 :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 set of parts or a rebuild kit. The number is usually found either as a tag or as a stamping in the body on the driver-side of the carburetor, running vertically up and down.'' ^1'' Should a need arise for decoding, please see the following article for further information and assistance: [[Rochester Quadrajet Carburetors: Identification and Decoding]]

 :A digital camera with a good flash will come in very handy. There is no need for a top of the line camera. Even today's cellphones with 5 megapixel or higher rating are more than sufficient. Become familiar with the camera you have and use it to photograph everything, from every angle, every step of the way. If you ever get lost during the rebuild process, you only need to flip through a few pictures to get back on track.
-:Remember, with a digital camera, there are no limitations on how many pictures you can take because you are not using film. And when you upload your pictures, be sure to organize them into folders and sub-folders with useful categories for titles, i.e. ''Removal'', ''Dis-assembly'', etc. Extra effort here will save a lot of time and headache in the future when you have go through the photos to match up the right parts or bolts.
+:The things you will need to keep an eye on are protecting the camera from grease and dip, and the battery life. Battery life varies from camera to camera, as well as the age. Make sure to keep the camera fully charged and as often as possible. If you keep the charger plugged into a socket close to where you are working, charging the battery during down time is a breeze.

 Safety is always a top priority in any project, especially those which require tools and chemicals. Be sure to work in a place that can keep out children and animals. When using chemicals, it is a good idea to warn anyone nearby of fumes. Please refer to [[Health and safety in the shop or garage]] for helpful tips and ideas.
-====Ventilation====
+=====Ventilation=====
 :Ventilation is very important when working with chemicals. For the rebuild, you will be using the Chem-Dip, which has strong fumes. If working inside the garage or other indoor places, be sure to keep the windows and doors fully open. If available, employ a large exhaust fan to suck out the fumes.
