damn little springs !!! 

look at it this way ... if the spring was not 
important to proper function, chances are 
Teletype would not have included it.   :)) 

congrats on finding that obscure solution.

ps:  too late now, but I was going to suggest 
that since you are sure that the keyboard is 
sending correct codes, turn the machine off 
but leave it in the local loop.  press a key on 
the keyboard and then slowly rotate the motor 
in the proper direction ...  as you rotate, the 
kbd should generate the proper mark and space 
sequence for the letter you pressed; as you do 
that, the local loop will be keyed, the selector 
magnet will respond; the code selection bars will 
respond to the selector magnet moving; and that 
bit should set up properly on the code selection 
bar of that bit.  When all five code bits have been 
generated by the kbd, the code selection bars 
should be in the proper positions -- if they are, 
then they are working ok; then you will have to 
continue manually rotating the motor and watch 
the typebox alignment and see if it is responding 
correctly.  This should all work in 'slow motion' 
as you manually rotate the motor.

A code bar or other item missing a spring should 
be spotted right away as it will not respond as 
it should.
