This scenario requires pulling the string up to pitch and leave it. 
There is too much friction to finesse the torque in the pin. Once you 
back down the tension, the pitch drops dramatically. So pull it up to 
pitch and leave counter bearing bar to tuning pin string
segment at higher tension, it will hold the pitch better.  Speed 
tuning helps too.
