My 2720 is fairly new to me as of last year.
The torsion bars were working, but I thought that they should have
slightly more "springiness" to them. That word is the mystery word,
as I am no expert with torsion bars, and I use it only as an indicator.
The TM was formerly stored in the closed position, and I thought that
maybe, right, just maybe, storing it upright for a few months might make
a difference in the "springiness" of the torsion bars.
Ok, the few months of being stored upright are over, and after raising it
and lowering it a few times in the last two weeks, the torsion bars do
have more "springiness" in them. The problem is that there is no way of
measuring "springiness", as it is a feeling. The raising and lowering effort
is easier, and feels more "springy". Yes, had to say it again.
So, based on my purely unscientific experiment, I can recommend leaving
the TM upright to let the torsion bars "revive" themselves. Right, another
mystery word.
It works the way it works, and it is what it is.
