Anyone know how or can point me in the direction of a procedure for the valve adjustment? My google-fu is apparently failing today.

Welcome to MLF jminton. I'm not at my main computer to look for that but I'm sure someone will jump in shortly with the specifics on that. Meanwhile enjoy the forums.

Welcome jminton!

By John Deere Parts it looks like you have a Briggs 407777 twin on that.

Here's the engine owners manual if you don't already have it:

and although this service manual is for Generac I think it is the matching engine you have. Page 23 (25 Actual) starts the valve adjustment procedure.
