FWIW:

"If" one wants to experiment with a few things that "really" works, and will not harm metal for cleaning cast iron carburetors or pot metal carburetors :

1. Cast Iron or Pot Metal:

POR 15 "Marine Clean" is a water based chemical specially formulated material that attacks petroleum products like paint remover attacking dry, cured paint .......... it emulsifies petroleum products as opposed to thinning petroleum products. It reaches deep down in the pores of metal where afterwards, the emulsified petroleum residue can be rinsed off with water. After said use, (sometimes with more than one application), the metal is "oil free & petroleum product free" ....... hence, it will rust quickly in humid areas if not treated or painted to seal metal pores.

2. Non-Ferrous Carburetor Screws and Jets: Used successfully only by vintage mechanics that I knew since the Model T days:

A. For non-believers, please find the most tarnished pennies one can find and allow several of them to soak in two (2) separate solutions.

a. Solution A: Your most favorite and strongest Carburetor Jet and Carburetor Screw Cleaner.

b. Solution B: Louisiana Hot Sauce.

After 10 minutes soaking, please, please, look at the pennies in each solution.

Hmmmmmmmmmmmmmm .....

Besides steel wires, wire brushes, lacquer thinner, carburetor cleaner, etc., etc., ...................

What was in "most" mechanics' shops for cleaning insides and outsides of Carburetor Jets for the past 90 years?
