Valve body comparison. First variant exhaust section on a 13-XX intake section, at left.
Stock 13-XX at centre.
Stock current 2200 at right.
This is what a blown pumper valve stem looks like. Part was already 40+ years old before I subjected it to more than what it could handle.
I think the tube was damaged on this little escapade~ I can't get any valve to hold air inside it. I'm going to have to get another tube...
