So my bike sat for a while with crappy fuel, tried to start it, fuel started spilling out of the air filter (lunchbox). Floats spring was obviously gunked up. Carbs were full of green goop. Go it all out, but I had to easy out the screws that hold the floats in. Needless to say I need to replace them. I don't want to order them from bike bandit or anything, because lol $10 for 2 screws.

Is there a type of material I should use/avoid?

Thanks all

Edit: Nevermind, reading is fundamental - INSIDE the carb body.

So anything should do?

Anything is fine. Steel, aluminum, etc. No big deal.
Yea that worthless screw is always tightened in like it was the lug nut on a semi truck.
Cool.
