Like JohnRR said, it looks like I need to lengthen the flat bar with the slot as well.
Nice work , almost there.
the back of that slot needs to be against that post with the arm and linkage from the trans pulled all the way forward , that's what the spring that you don't have installed yet does .

Thanks for the kind words guys. I would feel a little better about it if it hadn't had taken me 3 hours to do it!!! 
I have another problem/question. The lever arm on the transmission requires 1 3/4" of travel at the slotted bar to move it from it full forward position to the full rearward position but the carb only has 1 1/8" of throw.
Do you start by pushing the arm all the way forward or just letting it go back to its "home". When I measured the distance needed to move the lever from its "home" to the full reward position it's 1 1/8" (same as the carb).
Here is the lever after it's pushed all the way forward.

And all the way rearward.
Does the lever need to travel the entire distance (fully forward to full rearward)?

It doesn't need to go all the way rearward , within an 1/8" would be ok , 1/16" would be better. The back of the slotted rod must be against the stud when the throttle is at rest with the lever on the trans at it's full forward position , idle position , and begin moving as soon as the throttle starts moving all the way to full throttle.

That's what I thought but I believe I have a lot more than 1/8" of travel left after I get the carb to full throttle. I didn't think to measure it but I'm guessing 1/4" or so...
I'll measure that tonight and post the results.

Can you adjust it any or is it at full adjustment ?

It was at full adjustment and I still needed ~3/4" movement in the lever but I bent the one piece rod to "shorten" it which moved the pivot point at the throttle bracket. After I did that I was able to get the full throw that I need (push lever forward, back of slot touching carb stud, push carb stud to full throttle and lever at trans moves to full rearward position).
Thanks JohnRR and all others that helped.
