If you are going to swap out a carburetor, it is your responsibility to research the swap and find out everything about it. Many jeepers have done this swap and rave at the performance and mileage it gives. They even list and document exactly how to do it. (Search for it here or on Jeep Forum.) You should have also bought a manual on the carburetor. I don't believe anyone has ever said, "Drop one in from a Granada and let it run. It will set itself."
Please don't misunderstand me... it seems you want to do this for the right reasons but you took a "low ball" way to do it. Changing carburetors and fuel injection systems ALWAYS involves other procedures because no two carbs are identical and no two fuel injection systems are identical. You have to do the work (mainly the research) to find out what to do correctly. It isn't simply bolting on the carb to the manifold. Good luck with this build. I believe that once your carb is "dialed in" you will enjoy it a lot better.
