[Fot] Overdrive issue

[Tony Drews]

I thought you might be interested in my continuing OD saga.

Thanks to all for the excellent advice!  I took the OD mostly apart 
and documented my findings on the overdrive page I created:
http://www.tonydrews.com/Overdrive/overdrive_problem.htm

What's amazing is that the OD worked just fine at the last race.  If 
you look at the pictures on my OD page, you'll be amazed that it 
worked at all (I was anyway).

Also, Randall sent me a PDF of the Laycock A-type overdrive manual, 
so I posted it on that same web page, along with links to Larry's 
excellent tranny and OD articles.
