Consew 118 walking foot problem

[Mark59]

Hello.  I am restoring a Consew 118 walking foot industrial sewing machine.  The outer walking foot will not go up/down.  The inner foot goes up and down.  I'm trying to figure out how to get the outer & inner walking feet to work properly.  I have posted my first ever YouTube video illustrate the problem.  Any help is greatly appreciated.  I've been tinkering with for weeks now and am frustrated.
