Al, they adjusts with a metric hex instead of a screwdriver - they
operate just like a G250 inside. The problem is not the seconds, it is
that the poseidens creep, but slowly. The o-ring under the seat gets
hard, and any dirt in the reg mugs the piston to where it does this.

The thing will operate somewhat properly up to about 190 psi before it
ff's, and then the i pressure of the posieden drops back and it just
hisses. This fooled me a bunch of times where I kept changing out the
second until I threw a guage on it and saw it first hand.

Due to the shape of the poseiden piston, like a little pecker, and the
seat, like a , well, nevermind ( they are Swedish ), it rarely just cuts
loose and freeflows full tilt boogie.
