Alright so I am trying to run 15psi, according to some internet source I have to use three different color springs and I had to use a press to put the screws together lol. am I doing something wrong? what color spring should I really be using?

 

I was trying to figure out the same for mine.i had found two different charts online,but I used my air compressor to make sure they were correct ant those charts were way off.so I just kept swapping out springs till I found which ones worked for me.i was aiming for 11 psi,so had my compressor set at that.

 

maybe I should try that
