Hi Rogerio,
               This may help.  The coil determines the force, the geometry of
the spring determines the direction of the force,.

Now look down through the action and make sure that all the springs line up
like toy soldiers.  This will ensure that all spring forces are reacting in
the
same direction.
With butterfly springs, The friction in the spring slot is critical.  So
remove
a wippen and make sure the slot is clean, burnish with a pointed hammer
shank, 
clean the tip of the spring.  With the spring out of the slot, check the
centre
pinning of the jack for friction.
Reassemble and re install. Check the condition of the knuckles, light  sand
with a strip of 3/8" strip of sand paper if needed.

Now try and regulate, and let us know the results

Regards Roger

PS. this was a major item of Gina's and my, Interactive grand regulation
class.
It will be covered in greater detail in the Sept Journal.
