ive been using my eBaron dripper atomizer on my 3 yr old grand for months now with no problem. i bought a new reo grand LP and when i screw down the atty down my new reo shorts out and spring collapses. i had couple of spare springs and after i installed the second spring then pressed the fire button it shorted out again, collapsing the spring once again. now after the 3rd battery spring i reinstalled the atty and stopped turning after the lightest resistance and hit the fire button and seems to work just fine. but now theres a 2mm gap at between atty and 510 connector. it puzzles me cause on my original grand i screw atty all the way down and everything works great, with no gap at all. any ideas? thanks.
