I bought two Aspire tanks last night, one of them has the center pin sitting just slightly below the threads the other one has the pin sitting above the threads. Was there a defect in manufacturing. The one with the pin within only fires on my sigelei 100w with the pins adjusted. None of my hybrid connectors mods will fire it or my nemesis. Is there a way to fix this? I have no issues with the one that has the pin slightly below the threads.
