Every single Carter TQ carb kit (gasket, seals, etc) instruction sheet I have ever seen (and I've got about 10 different ones I'm looking at right this moment) had one of the following statements:

"...All original metal float settings of 1" or 1-1/16" use 29/32" when plastic floats are used..."

OR

"...Applications with Cellular float (not brass) set 29/32..."

In general the kit instructions will show an OEM setting for a given carb model year because previously brass floats would have been used befor the nitrophyl stuff came out.
