The load moment at level is 67.55 lbf*in. With the 10" member
horizontal the diagonal spring is at a 16.7 deg angle from
horizontal. It will therefore need to exert 23.5 lbf to balance at
level. Extension at horizontal is 2.15", so spring constant k is
10.93 lbf/inch. To balance "slightly above" level the spring constant
will need to be "slightly greater".

Trying to set this up in a spread***. Is the spring force the
moment/(Sin(A)*arm length)?

Yup.
