TR6 Choke Cable

[Dale VanCleef <dalebonn@netnitco.net>]

List,
I recently purchased a choke cable from TRF.  While installing it, I 
noticed that the cables are made of twisted strands of wire.  The old 
one had solid wires.  Stranded wire cables cannot "push" very well.  
Consequently, I can apply the choke... but I cannot release it (shut it 
off.).
So:
1) Is there supposed to be some sort of spring return on the choke?
2) Am I missing something obvious?
3) Is the $45 cable just wrong?

Thanks in Advance,
