Tweaking is not what you do with Cockers. Replace or upgrade yes, but tweak, NO! Put it on, set it right ONCE, only adjust if not working right. If it cycles quickly and smoothly, doesn't use too much gas, chronos consistently, and doesn't chop DON'T DO ANYTHING TO IT AT ALL. If you have to duck tape your non-shooting hand behind your back while playing and be put into a straight jacket after games DO SO AND AVOID BEING A MORON. If you fuX0r your Cocker up after it works perfectly and I find out about it, I may have to fly over to where you are and smack you in the face repeatedly with a stalk of cauliflour until you reach your senses and learn your lesson.
