Carter Carb tune-up tips
The feedback system is not troublesome in the least. It is a fairly complicated system, but if you take an hour (or less) to read the TSM and uderstand how the system works, you will better appreciate your car. I've had four Eagles equipped with feedback carburetors, and none gave me any more trouble than any other carbureted car. The feedback systems all worked perfectly for many years and hundreds of thousands of miles. If you must make adjustments to the carburetor, be sure to adjust it exactly as instructed in the TSM. Better yet, if it ain't broke, don't fix it!
If you are having problems with your car idling poorly, check the bolts that hold the intake and exhaust manifold to the head and make sure they are tight. Next check all vacuum hoses for proper routing and condition (not broken or leaking). If you still are having trouble with poor idle, clean the carb while still on the car, fully assembled. Clean your carburetor with a can (or two) of aerosol carburetor cleaner. Pay extra-close attention to all the small holes visible down the throat of the carburetor, and pay even more attention to the idle air bleeds in the venturi hold down screws. These holes allow air into critical areas of the carburetor. If they are dirty, the carburetor can not function properly. My experience with this carburetor is that it works, and works very well, in both feedback and non-feedback models.
