Uhhh... I think the spring you mean is located at roughly where the
two 'arms' of the levers holding the heads meet.  It's there with some
red glop on one end and appears to pass from one side of the lever
assembly to the other.

I can see the upper end of the spring.. but not the lower end.  Will
have to find an inspection mirror to peer underneath.  The upper end
has some red glop on it.

I'm a little nervous about removing the head assembly.  Without an
alignment disk and software to run it, I doubt I'd get the heads back
to where I could read 'em.

Thank you for posting the jumper list.  Very much appreciated.

Regards,
Mark
