[GreenKeys] Model 28 Ribbon Winder Adjustment

[Richard Knoppow]

    A guess only, it might be tension. Its possible for the reversers on 
some typewriters to reverse because there is too much tension on the 
ribbon. Now the question is where the tension is coming from. Check the 
fork the ribbon passes through to see if the clearance is the same as 
the working one. You can also try holding back the spool that reverses 
with a finger to increase tension and see if it makes it reverse.
