I just bought a brand new 4 Barrel Rochester M4ME 750 CFM with electric choke to replace my old Carter AFB performance series carb that was on my 1974 full size blazer and i was looking for some install information, for the electric choke mostly...but some vacum diagrams would rock as well...thanks all.

First off, don''t type in such a large font. That will keep people from reading it.

As far as the electric choke, Hook the ground wire to one of the screws that hold the choke thermostat on. The positive wire will then go to a +12v source that is only active with the ignition on. Vacuum is easy. Hook up the vacuum advance from the distributor to the port that has vacuum at idle and through the entire rpm range. Hook up the brake booster to one of them also. The PCV just get hooked up the the port that is usually on the front of the carb.
