Gary is thinking you might be trying to use plastic floats in brass float bowls, if there's a difference, which he's looking into.
I can't follow which has been whittled on, what works on a bench, and so on. The floats in the picture have that sleeve I was talking about, the little black tube. Without that they're not reilable.
I don't suggest you do this, at least not yet, but I had a needle hanging in a seat for some reason and not going all the way up to shut off the flow. I took a pocket knife and made a very light chamfer around the inside of the neck of the seat, which cured that. Don't let any shavings get in the seat or bowl.
