Carb flooding

What's the float made of? Is it brass or nitrofil? If it's nitrofil, you can dry it off good and gently squeeze it with your thumb and index finger and release it. If there's wet gas finger prints left on it, it's saturated with gas.
It’s nitrofil, squeezed it and no prints, seems dry, this is how it’s sitting, this is my first carb rebuild
