Hi Guys , i recently received a GT 2 clone from fasttech , i cleaned it built it etc , but in my opinion the draw is too loose i have wrapped under all the apropriate orings with a thin strand of ptfe to make em tighter , so all seals are good and solid but anything past two air holes showing is exactly the same , am i missing something or is the gt 2 aimed at lung inhalers , as opposed to my mouth to lung?
