I have previous experience with the CE2 Fluxos as I bought my first ones for my KR808. They work perfectly (I do know about removing the inner cup seal, using the O ring instead) and have not had any problems with those ones whatsoever.
I have since moved on to a Kgo, so I ordered up some 510 Fluxomizer Deluxes. I have tried two now, did the same exact modding as I did to my 808 version. I left each to wick for awhile before going to town on them and when I came back 1/2 the juice was on the table. I blew out the juice from the center channel. I did not get any juice down the center while filling, I make sure I do not. They were both set vertically.
I'm not sure what is going on I have searched a ton before posting this, can't really find a solid answer. Even after blowing out the fluxo it still begins to leak out the battery end. Not from the tube itself. I even see it seeping out the small holes on either side of the battery connection. I filled them to about 1/4" below the ceramic cup. Any thoughts as to what I'm doing wrong here?
