Unhook your throttle pedal linkage at the carb
Rotate the carb linkage arm to full throttle, notice how inside the carb the throttle blades are standing straight up, this is WOT Wide open throttle
If your throttle pedal is all the way to floor, compare the distance from the carb throttle pedal mount at WOT to where your cable is......the distance between these two is what you need to adjust to achieve WOT

I use the "Unwatch" button a lot lately.

that's one that gets me the most. not even an attempt on stuff.
my seat track is all janky! how fix??!!??
how about looking under there? maybe giving it a squirt of WD and jiggling **** around?
it's like he thinks there's an "easy button" for all the little irritating details; which let's be real, irritating details is what owning a classic car is.
you could fix half this **** with an ikea tool set, some duct tape and zip ties and using the search function, you tube and a FSM.

Not everyone has a bunch of spare time to jump on things right away. Even worse, when an issue gets snowballed into hundreds of different possible explanations - it's tough to choose which one to tackle first. Even tougher yet when you didn't build the car and haven't wrenched on vintage ones for many years. OP is willing and that's as important as anything else.
I think too many people are way too high on their horse. The OP bought a nice car, and paid people who seemed capable. After the fact, he learns he got shafted to some extent. It happens, but everyone throwing their $.02 in doesn't help. Also, he didn't build it so it's not like he has the knowledge of exactly what is what - he's having to research every damn thing. It's equivalent to buying someone else's project without a build summary or parts list. It takes a while to compile the 'simple' knowledge. Lots of us can rattle off exactly whats in our cars, but OP doesn't have that luxury at present.
There's a few questionable things on the car, like the regulator placement, but it's possible to put it there and do a neat job of it. That's not what his shop did, but it's not a priority to fix anymore since the leak is taken care of.
The throttle cable issue is a risky one. It's not just a matter of fixing the cable - the trans cable also needs to get setup properly. Get it wrong, and he could burn it up. I'd bet dollars to doughnuts the trans cable is holding the throttle from opening all the way, and that most other commentors don't even realize it's not a 727/904.
OP did try to address it and got it to open further but it's obvious the secondary butterflies still aren't getting actuated because they only open with the last 10-15% of throttle travel, and can also be limited by the choke system when those carbs are cold. I went looking to find a guide for OP to set this up properly, and lord help the newbie trying to find the info because it just isn't out there in an easy to digest form.
Give the OP a break or he's likely to simply disappear from the site. Being a business owner also comes with time demands and struggles, so it's not like he's going to be back on here a dozen times a day with updates like our more retired members get to LOL.

i understand and appreciate all of that. especially the kickdown for trans, which is nigh impossible to talk somebody through-- and the OP is taking to a trans specialist so, good job there.
but seriously, on the seat? it took more time to post about it than to probably have a look at it and correct it. or to ascertain that "X" is broken, how to i repair that?
i firmly believe that everybody has the ability to learn, but sometimes it just seems that they don't want to put in the most basic of effort or time. like, pour yourself a tall one and sit back and peruse the forum and youtube. refamiliarize yourself with the things and processes you kinda sorta remember from way back when.
going in armed with even the smallest amount of knowledge helps tremendously.

no offence but now you’re high on you horse too. See how easy it is.
the OP said he had basic knowledge of how carbs worked, etc and that in his past he did this kind of work which if true I dont think you could never forget how a carb worked, but I don’t think so. Look at this picture again. This is with him pinning a 2x4 between the seat and the gas pedal.. the primaries aren’t even open 20% let alone the secondaries from any source be it the gas pedal or choke lockout etc…..

I would say that's fair, if someone built the car or has recent experience. But as OP explained, he bought the car and took it to have it made into what he wanted. He received it during Covid which complicated everything and once he finally got to see what he paid for, it wasn't what he had in mind and also had no idea where to start looking. It may seem obvious to those of us who play with these things daily, but a guy whos a decade or more out of practice needs a little help to get started..

Yeah, everyone's seen it. It's been called out for a while and even OP knows it's an issue but he's hemmed by what he's got for a linkage and kickdown system. I doubt his local corner store has edelbrock kickdown adapters in stock, so he's not going to get it knocked out in an afternoon. The limited throttle movement is likely a result of the kickdown cable, and he's wise not to want to go monkeying blindly with that.
He's going to a trans guy monday to have it looked at, which should help get the situation resolved. Assuming the trans guy isn't a 17yr old with a 'certificate' from the internet on how to look at scanner screens all day.
I'm one of the ones claiming to be capable of fixing an unfamiliar system in '5 minutes' because I know that's a stupid claim, so no I'm not on my high horse - I'm calling assholes assholes, deservedly. I also understand OPs position. He's dealing with an unfamiliar combination of parts after a lengthy and unfortunate series of circumstances and is now being hounded for not engineering a whole new throttle and kickdown linkage in less time than it takes to make coffee. Gimme a break...

Agree 100% No reason to pile on the guy.
I would love to see how this car ran at just idle.
Disconnect all the linkage.
Set the correct A/F ratio.
Set the initial timming between 12-14
Let it warm up, and give it a couple raps at the carb, and see what it does.
More than likely its something simple.
Carb pump nozzel clogged. (Not getting gas)
Bad plug wire.
Vacuum leak.
Incorect timing.
Something simple, but if you don't have a lot of knowledge, it can be frustrating.

no, he's not being hounded. he's been told the existing linkage has (clearly visible) adjustment slots to get to full throttle and he's not done it. maybe he should ask the trans' specialist to adjust that when sorting the 'kickdown' side of things. he can only ask.

That won't do an ounce of good if the trans cable is limiting things, and it likely is. As others have pointed out, the Edelbrock linkage often needs additional parts to get the ratio right. Just sliding the bracket may not be the solution.
Every adjustment requires another adjustment and he's held back on blindly doing things because the internet told him to, which is a good call.
If I may.... 
Following..............
I agree...BUT he needs to get the tools out. I think we're dealing with someone with very little mechanical aptitude......and there's nothing wrong with that. Hell, nobody knows everything and I'm sure whatever the OP does for a living, he's good at. We caint all turn wrenches for a living. I get it. But that throttle cable dealio is a five minute job.....maybe ten if you've never done it. I know that's easy for me to say having been a mechanic and whatnot for forty years. I want to see what he thinks once the throttle is working right. I bet he gets a big smile on his face.

That's a valid point, but even people with tons of aptitude can smoke a trans if they don't know exactly how it's supposed to operate.
Hell, I have no clue how I would set a 518 and would probably be here asking a million questions before monkeying with one. Not that I would build an auto car, but that's another topic, haha.
You're 100% right though. Once it's right, op is going to have an even harder time parting with the car..
I'm hoping he strikes gold Monday (he's due!) and gets a trans tech who is worth 2 ***** and helps get the kickdown AND throttle squared away because a good one should be able to without question.
Oh sure. I have tons of automotive experience, but I'm often the first one to slam frig something up nine ways to Sunday.
I wish I was local to him. I'd fix him up .

Same, its how I learned to fix things.. Because I was usually the one who broke it. Lmao.
With as much as OP has riding on the car, I can appreciate his apprehension, especially if his skills are a little rust (or worse).

The existing linkage is so cobbled together, that no adjustment is going to be right for it. The existing linkage needs to be removed, and thrown in the trash.

Probably. It's possible some of it could work, but it doesn't matter really. Someone is going to need to fiddle with getting the right ratios on the throttle and the trans to make it work together. One of the things that make non factory combinations a pain to dial in.
SOMEBODY BUY THIS CAR!!!
IMHO - The OP shouldn't fix anything. Someone with the skills to make this a truly great car should make the OP a good offer and drop a really potent small block in it.
