try turning the spring and collar at the same time, by hand....
a drip of oil on the bottom spring seat will help with this...
is the pre-sag (rider sitting on bike, not riding at the time) percentage known? have you measured it, then compared it to the total shock travel available figure?
about 25 to 30% is typical..
if the shock continually bottoms out, you probably need a heavier spring rate... if you dial in the sag, but the shock NEVER uses full travel, then you need a LIGHTER Spring rate.
i put a small zip tie or bread sack twisty on the shock shaft, and enlist a helper for sag settings.
