this seems like an easy fix, but I'm stumped!
so i tried to put a simple dispensing line (QD+tubing+picnic faucet) on a corny keg last night. the problem is, the QD wont "catch" onto the beveled edge of the kegpost, so i have to press+hold the QD onto the post while at the same time opening the faucet to pour. it almost seems like the QD is too short/post too high and the ball bearings won't reach past/lock onto the ridge of the post. i tried to lub the post o-ring and tighten the top of the QD, should i try to replace the post o-ring? any other suggestions, this has happened once before too......
