My brother has a Nova I'm trying to help him out with. He can shoot a string of balls then the spool valve will stick. Sometimes he can manually push the barrel in and that will unstick it, other times he has to take the barrel off and push the spool in with a pencil. Any suggestions on what I might do for this issue?

He's replaced the orings but for the second o-ring from the tip of the spool he was not able to find a 109 poly o-ring so he used the 109 buna ring like the one that goes in the third slot. Will this o-ring cause a problem? I haven't had much luck locally finding a poly 109 o-ring so if I need it does anyone have any suggestions on where to look?
