FWIW, I checked both an old spring and a couple of new ones last night, with
my digital fish scale. Didn't have a number for installed length, so I just
pulled them out from coil bind. The new springs took about 4 lbs to pull
1/4", the old one a bit less than 3 lbs.
Doesn't really help with your problem, but I think it indicates that your
old springs were pretty close to correct.
Sounds like you've got your jets & seals really slicked up. Hope they stay
that way.
