Aluminum heads?
In Post one; where are the throttle valves when this begins?
Is this at WOT, part-throttle, cruizing, where?
Is it related to a particular rpm, or just to throttle input?
Does it get worse in each successive gear?
Does it go away immediately if you back off the throttle just a bit?
Put a vacuum gauge on it, in the cab, or on the windshield where you can see it while driving, then go for a roadtest, keeping an eye on the gauge. Is the issue related to a particular vacuum level?
Are you running a Vacuum Advance?

I was hoping you'd chime in but think I got it figured out. Took Tonysrt advise and went back to basics . The carb is a rebuilt. the fuel/air sets don't really do anything at least not to feel any fade or rise , so I pulled the filter blew it out ,then the fuel intake port then pulled the mixer screws and blew a little air in the ports put it back together
started it up and took her for a spin. It was like night and day. Dirty carb.
The things on its way out. I took a video but can't seem to transfer it.
