Trust me, don't attempt it. The best you can do for what you have is make sure it's the carb. Why I say this is because these cars came with miles of vacuum line and a majority of it is more than likely cracked and broken.
These cars also have a MAP sensor, it's just not under the hood, it's ran to the kick panel on the passengers side front, under the glove box to the right. Check the vacuum line going to it, you'll find it's likely broken as well. Once you fix all the vacuum leaks it has then see how it runs.
