Guess what-I found the blade holder on a second visit to the recycle centre. Had to pay for it but it was still worth it. Went to work on the mower and it wouldn't go. Opened the valve cover and both rocker arms were completely disconnected from the push rods and valves. Used information on another post to set the valves and now it purrs like a kitten. Big thanks to all those here and on the other post.
