I thought at first since they torqued the atty together at the factory that they messed the orings but thats not the case. The juice IMO is getting past the bottom oring and seeping behind the airflow controller then onto the 510. I see no visible juice on the airflow or inside nor on the positive pin, just ontop the 510 like with kayfun seeping through the fill port. These merlin orings are thin and sketchy to start with. Once I cook the coil I'll take it apart again, re-evaluate the orings and try again. If I close the juice flow and airflow then it doesn't seep as much but still seeps so maybe the vacuum is pushing juice past the rings...I dunno until I take it to bits and try again.
I have 2 merlins and they both seep the same, one not as bad as the other to add another piece to the puzzling.
