Thanks Wycke, I tried this and thats how I acheved the 200-220 fps I've put light springs in and heavy springs and every in the middle. from my reaseach a stock 97 cockers pressure was still high pressure (900psi) and I cant get the thats with the valving. Should I start mixing the Nelson (pre 2k cocker) spring kit in an attmept to hammer the valve open for longer?
eg. light valve spring, heavy main spring
