Can you post a few pics of your engine bay? Maybe theres something your not seeing that may be obvious to someone else. I know that this can possibly lead to "opening a can of worms" as some people may start questioning your setup. And that can spin off into another direction. But I think those of us who have been following this thread are just as curious as to why your truck ain't running right and want to help you figure it out. And without actually being there and only your info to visualize what your working on. Pictures do a great job of showing more of the whole picture.
Personally I take tons of pictures before,during, and after I'm working on something. I didnt always, but wish I had. Helps remind me of those "oh, I'll remember where this goes or how this looks when I put it back together" Times that I forgot how it was before I started...lol.

I will try this and get some pics. First I am going to check my ignition coil when I get back, that I have not replaced. If the coil checks out I may throw the old condenser back on it just to see if that changes anything. Ive heard of people getting lemon distributor condensers from the parts store. As far as carb internals I dont see how I could have screwed that up, I took it apart and checked with the diagrams so many times. If it were an adjustment problem I would think the issue would change slightly as I messed with it and it hasn't.
Ive read a (going) bad coil can have same issues as mine. I mentioned the last time I was driving it longer distance it was surging/loosing power at 45ish mph and I had to limp it home. The problem has progresses to where it is now and I just assumed carb problems. Perhaps it is the coil/condenser. I am getting spark to the plugs at idle but at higher rpm/load im not sure.
I do feel like I am just grasping but hopefully with what I have done I am narrowing down the issue.
