Is the one on your aircraft loose with a lot of play. Is this a problem if it has a fair amount of play but still seems to work OK.

What part of your selector is loose? The handle, the linkage universal or are the position detents missing?

I would expect some play in the handle to the actual control. The fit of each piece of the control handle and linkage is not a close tolerance.

On mine, the handle has some play, but when I turn the valve, it's movement is solid, smooth and tight. In other words, just sitting there, I can jiggle the handle a bit without moving the valve. On mine, it's just loose tolerances in the handle and linkage as Bruce mentioned.

The whole unit itself seems loose down below the floor and can therefore be wobbled back and forth. The turning portion of the handle seems not too bad and there is a detent.

Helps to remind us what model 170 we are talking about.
Both the A model and B model are secured fairly well by both the mounting bolts and the 3 hard fuel lines that attach to it. Anyone who has removed one of these would say it's attached to well. So even if some mounting hardware was loose, I'd be surprised you could identify that situation from turning the valve handle.
It's pretty easy to remove a inspection plate and look at the valve while you operate the valve handle and see what you see.
