Hi and good day to all of you. i have a few question regarding above topic matters. i've bought this lotus modz clone. it was good firing with silver pinned and all that. until a couple of days ago, my mods started to miss firing. and i try to figure it out what would cause this miss firing and i found out that the spring get loose. so how for me to fix this spring? how for me to re- roll the spring?
