RE: [DMCForum] Re: One nit-picky question

["Travis Goodwin" <tgoodwin@xxxxxxxxxxxx>]

I'm talking about the little adjustment screw that you have to turn to reset
the piston. You have to turn it a quarter turn to allow the piston to go
back into place. What's bugging me is whether or not I turned the little
screw back so that the piston can extend as the chains loosen. 

And you're right, the chains are very tight and butt against the adjustment
arm that runs inside the tensioner. 

Like I said, this is just a thing that I'm 90% sure I did (I can even see
myself doing it in my mind), but ever since the infamous "Washer Incident" I
am obsessing about every little detail.
