The new kit orings have worked for me aswell. Altought i needed to build fresh shocks a few times. The o-rings might not be seated properly on new set. So I fill the shock full and close the air screw too. Then i press the shaft down firmly so i get hydrolock and see that it doesnt leak or suck air. After that make your rebound setting, remove extra oil, air bubbles etc. And throw away that airscrew o-ring. It doesn't hold in its place.
