Don't know if you fixed the problem yet. I had a '79 GMC, 305ci. I had similar trouble. 2 things were wrong with mine. I don't know if your aftermarket carb has an electric choke. I had to switch mine to a manual choke. I also discovered that some of the vacuum hoses had tiny cracks that were barely visable. I replaced ALL the hoses. After that the problem was solved. Really hope this is helpful.
