Yes, I believe it was this way before I bought it, that's probably why it was at a salvage yard. I don't know it's history.
One other thing I don't think is right, It takes a lot of force to push or pull the shuttle valve, maybe 50 pounds +/- and to me, that seems to be a lot.
Without taking it apart my guess is there is probably some bad O-rings inside.

Have you tried the valve without the linkage in place, it certainly isn't helping anything.
