I use 90% VG with a single hole (Boge LR's) and my AGR's (I have 2 of them) worked right out of the box, with no problems at all.
Sorry to hear about your problems...

Found a fix for that... cheapr clearos come with driptip that screws on clearo. Those got small silicone o-ring on them, so I've put that o-ring on carto and now it seals properly... no more leaking
But yeah, this does not fix flooding carto.
I found out the problem with one was the bottom locking piece lacked actual grooves. There were marks there for them...but the surface was smooth as butter. Obviously that isn't going to work.
Mine started leaking today. Found it was cause of the loose fill screw. Just a heads up if anyone thinks this may help. It's gotta be air tight in there.
Correct me if I'm wrong but isnt a tank just a carrier of juice. There isnt any way that a tank could itself flood your carto if you filled the tank properly and punched the carto correctly......right?
