If just your floats are sticking, you only need to clean them. I use a Q-tip with a bit of 0000 steel wool wrapped around the end. (take the cotton off first) Then twirl it a few times with you fingers and remove. Then use the other end with either Brasso or toothpaste to polish the seat in the same manner. Make sure the spring button on the end of the needle will compress and release, and put it back together.
