mickmep Posted November 4, 2013 Report Share Posted November 4, 2013 have you filled to the correct pressure ? some pcp's will run under power if there is too high fill pressure or too low. the s16s is not as easily tuned as the earlier models, but there is information out there to enable you to tune them. is the chrono accurate ? i had one of these, there is a good forum for them.

snarepeg Posted November 4, 2013 Report Share Posted November 4, 2013 What model is it,? If mk 1 the fireing pin that goes thru the block has a habit of vibrating out resulting in low power then none, it can be put right without going into the internals.

snarepeg Posted November 4, 2013 Report Share Posted November 4, 2013 That one as a set pin, so will not do what I said, hammer spring needs shimming? Take scope rail of and you can se the spring, lever forward with screw driver and insert a spacer, this will raise your power, hope this helps.
