ok. so i went to put the red O-ring around my Cylinders today while rebuilding it, and i cant firgure out if i should push it in the groove or keep it ourside and let it go in there when i torque it down. when i tried pushing it in, the it went in, but there was a ton op play and slack and the rest wouldnt go it. possibily a stupid question, but i gotta know. thanks guys.
