I just bought this ego a couple months ago an there's been maybe 2 cases shot through it....I recently put a dart kit in it an its been downhill from there..gun did perfect before the DART but now it won't shoot over 200 and the first shot is just a small burst off air(can hardly hear it) this just started yesterday...I need help bad because I'd rather not send this gun back and not have a gun for 3 weeks so any help would be greatly appreciated, I'd actually be willing to pay someone if your in NC
