Shaft Play.....?

[howslowcanyougo]

I know this is another n00b question, but thats what I am, and why I'm here asking you the "wiseguys" <in more ways then one>.....

Tearing out my Big 16G, and notice now there's some shaft play.

Nothing, side to side yet , but there is maybe 1/16 of "in and out" shaft play?

It seems to still spin ok?

Just how much of an issue is this amount of play generaly speaking?

TIA.......
