Haha, I told you re the mech, have you got a barrel adjuster? if not you've got no hope, after that just make sure it's in the right position with the lines matching up on the big ring. the arts cyclery tutorial is very helpful with it.
They don't mention it in the video but the guy mentions the tension and re-does the tension by having it in the little ring position. Having an adjuster just makes that step easier, the yaw derailleurs need a load of tension in the cable to work well, when they do work though, they're really good
