Sometimes [and this happened to me] the viton alloy needles are slightly to big for the seat. When I tickled mine the float would stay down [and the needle would stay up] until I gave it a sharp tap. I cured this by using some fine 400 grade emery and then polish on the three corners of the needles. This and a small amount of polishing on the top section of the seat fixed it. Note that I didn't touch the viton section at all, nor did I touch the actual seat hole or the area around it.
The viton alloy needles also have a slightly serrated finish on the corners, have a look at them under say 40X magnification and you will see what I mean. The sanding and polishing corrects this.
