Chuffing problem with X-valve

[paintflick22]

I am having trouble with my x that i put in not too long ago. Everytime i go to shoot, it chuffs once then i get a good ball and so on. I tried turning up the input pressure but it starts leakin down the barrel or through the hole on my flatline. Then if i turn it down,thegun wont even shoot. I tried an tried to get this thing fixed but it wont. I would like any kind of advice t hel me atleast get to play with my mag. Thanx Help is Appreciated.

First, try oiling it. Put 2-3 drops in the powertube. If that doesn't help, you have to change to a smaller spring. Which spring do you have now?
