[R-390] 1967 EAC S/N 4998 Cosmos PTO Question

[Gary I. Biasini]

I recently added a 1967 EAC S/N 4998 to my radios.  It was a bit dirty but
otherwise seemed in good condition and the purchase included the screwdriver
and bristo drive.  

 

In checking the PTO however, it was about 5 KHz long so I decided to align
the endpoints.  Unfortunately, when removing the cover screw, I didn't see
an adjustment screw.  The picture at the link below shows what I found.  Any
help as to what to do next would be greatly appreciated.
