hello mag'ers

i have an Xvalve in a ule body. When i gas the marker i get the first shot "pop" then the marker holds air but every shot after that leaks down the barrel. I notice it being slow on the "recharge" along with the leak

i have an Xvalve parts kit but i dont have the carrier set, just the one in the marker.

ive tried changing what orings "looked bunk" but no dice.

im open for anything now. thanks for the time
