Just took the shocks apart for the first time and tried to follow the associated video on how to build them emulsion style. When i take the bladder out of the shock i dont see any o ring in the cap like he says in the video. And sorry for the dumb question but if there is a bleederscrew hole why is there a little hole under it too. It leaks out of there. Not good with shocks only have built a couple before. Please fill me in
