Head Refurb or Buy New?
A replacement seal for the Wil-Crit is a pretty inexpensive repair. I too, had a 30+ year old Bydon Boy, which the pump and joker were completely shot. It was $50+ for the full rebuild kit, but I found a new replacement Wil-Crit for $99. Used the opportunity to do a complete rebuild of the head (new flooring, hoses), but it turned ito quite a project.
