2K5 Black Magic Pump Spring Questions
Just got my paws an a really nicely built 2K5 Black Magic autococker (the half block one) and am looking for some information on tuning. The previous owner did a nice build (CCM pump kit, 86 degree trigger frame with auto trigger etc) but seems to have not done the best job choosing springs (hammer and valve).
Now I know this marker uses the trilogy style valves, but from previous posts I have read that the valve spring should be a spyder spring and not a cocker spring. Is there any drawback to using a cocker valve spring?
Also, in my limited test firing I seem to lose velocity during auto triggering. Am I correct this is a symptom of poorly setup springs?
I currently have a cocker madman spring kit and a handful of various springs from previous cocker builds and purchases. I'm just looking for a little advice to help trim down the tinkering time on this marker.
