Alright, I’m now convinced no adjustment I can make in timing, idle speed, or mixture will fix this problem. All the vacuums seem solid, all the carb screws, bolts and manifold bolts are tight. I think the gas supply is good and the pump is new. So, I’m going to take the Rochester off, clean and probably rebuild it. There must be something stopped up or flow restricted somewhere. Thanks for all your help everyone.
