You may not need an entire kit. Take 'em apart and clean them up and see what you need. At a minimum, you'll want float bowl gaskets and probably float needles, but other than that you may be OK. Just depends on how long they sat with old fuel in there. I got the gaskets and needles from Parts N More (there's a link to them in the parts suppliers post).
