cocker valve spring question

[sbikeclix]

what year did wgp change the valve spring size, and did they make it longer or shorter?

[paintballtommy]

i believe it was 98 or 97 but dont quote me im not sure

I believe that the 99 and later cockers are Nelson-type spring compatable. This means that all nelson type springs can be interchanged with 99 and later cockers.
