So since you do not know were you are, you need help. If the bow is a 60 to 70 lb model, you can do the easier way is to start the bow out at peek weight, so turn the limbs bolts in till they will not turn, both on the top and bottow limb. Next if you want to have the bow at about 65, turn the bolts 3 full turn back, both on the top and botton. If the bow is still to heavy turn the bolts back again one full turn both on the top and the bottom. This should reduce the bow by about another 3 to 4 lbs of peak weight...let us know how you make out. Or take to a local archery shop and they can do it for you at a reasonable cost and you can see how they do it. I have people stop by all the time and I put on the shop scale and will increase and decrease weight for them at a $2.00 service charge, I use to do it for 0, but found time is money...
