I have a Montgomery Ward Signature 513(JP-3) that I am attempting to fix the escapement.  This has 3 eccentric screw settings, 2 in on the front plate and 1 in the rear that is unable to be accessed unless the whole escapement is removed.  Would love to know what sequence and settings that a manual might offer as this is one of the most frustrating tasks that I have encountered.  The carriage either runs free or is totally locked...can't find a happy medium.  All parts appear ok as there is no evidence of missing or broken parts.  I have been playing with this for weeks and am not getting anywhere.  I got this through SGW so don't know its history.  Hint:  When I received the typewriter the drawband was not attached.  So, if anyone could share the escapement chapter of the manual, that would be greatly appreciated.
