Check the tiller also. One limb might me weaker than the other. Just because the tiller is same doesn't mean it ok. Tiller is the distance between the back of the limb, just outside of the limb pocket, and the string. If the bow has a different sized cam and idler wheel combination, you will need to tie a thread from one axle to the other and use this as your reference when measuring tiller. In most cases, equal tiller will produce the best arrow flight and accuracy, but you can sometimes change the way the arrow comes out of the bow by adjusting the amount each limb bends when you draw the string. You do this by adding or removing turns from just one of the limb bolts, effectively making one limb softer than the other. Tiller tuning is dynamic and relies almost entirely on trial and error.
