My father-in-law has a John Deere 68 Riding mower # A684H # 097629M. It needs some TLC/ carb work. How can we find parts/kits/etc for this mower? Went to JohnDeere.com posted the numbers that I listed above nothing came up. Am thinking it is too old for their books??

Hi,
You could buy the manuals online, but it is to old to have them online for viewing.
The John Deere Parts Catalog will give you the parts breakdown at:
John Deere - Parts Catalog (http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.HomePa geServlet_Alt)
And I suggest the Sectional Index for easiest navigation. #1507 is the one. If you will provide the Tecumseh numbers off the engine, I will get you the kit number.
Peace,
Clarke
