on the cocking
there is a 3mm grub screw that put pressure on the bolt in the rear of the breech on some of mine i have put in white grease and a piece of felt and tighten the screw to get to right feel
i have also found that the bolts can be very loose and one would never know that they can be fixed
now on the hammer spring
the hammer springs should be the same but who know for sure without part numbers to compare it is a crap shoot and hell these are made in China batches of parts could be all different or not hammer spring changes and or shimming can be done for more or less power
my attitude has been who cares
now this picture is of a Trailscout but the breeches are more or less the same
i did find one that had a screw but was blocked by what i thought was a ball but till tonight never really looked
so, here is the picture of the parts and there is a rubber ball the grub screw tightens against and not a drop of any lube present
that is all i have for you
take out the ball and add grease a piece of felt and add grub screw and adjust
