I would pull some plugs and make sure they are correct color; near white to tan w/o deposits.
I would do a quick linkage binding check.

That's the procedure I followed on the idle mixture as well, it just seems odd to me it would have came out of adjustment out of the blue. Linkage moves free, the problem of it temporarily idling high after adjusting the idle speed went away with adjusting the mixture. Ill pull the plugs tomorrow and get some pics, thanks for your help!
