Thinking more on this and I want to be helpful so - some things I want to add/restate:
Yes you got the geometry corrector for the carb throttle. Good - but if you don't have the correct carb base plate bracket where the TV cable and throttle attach the geometry is still going to be wrong.
For the TV cable to work properly its about length of pull and tension - see post 41. If you don't have those angles correct it is not going to operate correctly. I don't know how you get those numbers by using parts that are not made for the correct application. Sure you can fab it up but those are the number you need. Or just buy the bowtie OD setup i referenced and also shown on post 8. Please note that the cable is supposed to be TIGHT.
Since you asked for the pressure test readings please see here:
