[CAUT] Pulley keys.

Hi Tim,
                  By comparing it with adjacent keys.   Quite often I will 
just use the glue size on one side or end of the hole.  I am not sure if 
our dryness has a bearing, but I have found no sticking.  Or maybe the thin 
coat of Protec grease on the BR pin prevents the sticking.
To answer Wim's question: Zero movement is acceptable.  Any movement, and 
you can hear a slight click when the back check engages.
