Needed to reduce the power on the 98 , she had slowly been going up , on a recent chronoing I had a reading of 812 fps which is just over 12lbs , so needed to reduce the power, general advise was remove 1 spring coil or compress 1 coil by heating and collapsing , i decided to remove 1 coil below are the step by step actions to get at the spring
Remove the scope
remove the trigger guard
then cup the area where the safety is , as when you slide the trigger mechanism it will pop out, your hand will catch it, remove the pin and the spring.
the trigger block holder needs to be removed now , for this you will need a rubber ( eraser ) the block twists out anti - clockwise, place the rubber down and stand the gun on it , press down and twist and the block should turn releasing the lug, at this point the spring will push the gun up- there should not be much pre-load on a standard spring but if your gun has been apart and some one might have put an ox-sping in be very careful.
