only stock spring (brass) works

[Spleen]

Hmm... Ive been trying to get the other springs in my xvalve.. So far, the only one that works is the brass one. When the other ones are in the gun will not fire. Is there anything i should do, or should i just leave the stock on in there? The only reson im trying to change them is sometimes ill get bolt stick (rarely) and i chopped a whopping 2 balls yesterday. 1 was because i didnt oil it before i played i believe, and the other ????..

turn up the velocity. They all will work, just stiffer springs take more pressure. And are you sure that you chopped the balls, or did they break in the barrel. I have never chopped a single ball with the short spring, although with bad paint I will still break them in the barrel. (had a bad batch of TC viper venom yesterday that broke in everyones guns).

And yes, bolt stick is because you didn't oil it, and possibly too tight of a carrier if oil doesn't fix it.

I second what speeddemon said.
