'74 Duster - stalls easily

Go here and download the 72 Duster service manual. I know. It's 72 but that's the latest they have. It should get you in the ballpark. Then, follow post #7 to the Nth degree. Once you get it in proper tune, see if it's not fixed. Report back with what you find. Here's the link for the service manual. I'm sure there are differences, but it should get you close. Just scroll down and find it. It's there.
