Is the wire seated (lightly) against the guide rail bushing?

The highest bass damper on this small grand is one where the damper is
way offset from the others to clear a plate strut. So the damper wire runs
straight back parallel to the head, then takes its right-angle bend down
through the guide rail. Trouble is, it rattles, or "twangs" when it settles onto
the vibrating bichord, almost like a nano version of twanging a ruler on the
edge of the desk in grade school, to get that "doing-oing-oing-oing-oing"
effect.
No, the head is not loose on the wire. No, the hole in the guide rail isn't
too big. The piano's only a few years old. No, the screw in the damper
block isn't loose. No, the damper wire isn't contacting the head -- it runs
along the felt, but not right against. it. Yes, the damper lifts and seats
straight up and down without twisting.
I just don't know what to do to get rid of that "duhd-d-d-d-d-d" noise
(to use a technical term). Maybe they didn't use a stiff enough gauge of
damper wire?
