A student mixed up the valves on her YEP 321, and I can't for the life of me find the numbers marked anywhere on the valves.
Is there something I am missing?

Never mind, I figured it out.
I was trying every combination of valves and getting nowhere.
She apparently unscrewed the 3rd valve stem, and reversed the orientation of the valve guide. I have no idea why!
Is there any reason that they have two "guide holes" at the top of the valve???

One is a guide hole, the other is a vent hole (to the bottom of the valve).
