Typically it would be coarse thread where the stud goes into the manifold and fine thread where the nuts go on that hold the carb. A lot of them are 5/16", some are 3/8"

It's certainly UNC into the manifold - just not sure if it isn't also UNC to the carb.

When you've found the thread, remember that you need half-nuts to hold the carb on.

Thought the last thread post was the "last one, honest"!!
3/8 UNC in the manifold, 3/8 UNF on the carb end.
