Well, there are a number of ways you can go about it, a lot of the approach depends on the starting point, that being the actual TQ model# you currently have.

Yes, it is easier to get there if you start with a nonLB carb, but this is doable.

Here, take a look at my complete CarterTQ library. I zipped up the whole structure of what I have in my private archive, it is about 250M in size so it'll take a while even on a fast internet connection.

You will find a boat load of info there, including diagrams of the fuel circuits, Carter Tech Guide, etc. Point being, if you want to learn you certainly will have all the information you need, and as you progress through the modifications you can track your work in a thread here.

On the other hand, if you are looking to send the carb over to someone to have it worked over, that may be a challenge today.
