Air leaking out the back

[TAC-ELF]

...With a X-Valve you fire a shot, hold the trigger back and quickly release a shot over the chrono. This simulates rapid firing. Since the valve recharges so fast, it should be tested this way. To test a X-Valve like a normal valve would give you incorrect readings.

What kind of oil are you using?

What's your setup?

Yes, it's an Xvalve with the following marker setup:

- Spring: Smallest that came w/ my Level10. The "middle" spring won't let the gun do anything right regardless of velocity adjuster's setting. It either won't fire, will run-away w/o paint, or will jam open if there is paint.

- Velocity adjusted to average about 275fps. Important to note that the velocity adjuster is turned almost all the way clockwise.

- Level10 tuned properly: No leaks using the largest possible carrier (same oring) [next carrier up leaks when I gas up], 2 shims. Tried with zero shims, no difference.

- ULT assembly: 2 shims. As I'm not precisely sure what this does I left it as its default settings. All I know is the trigger has a nice light feel but don't really know what role it plays in the whole system.

Marker oil used:
- Came in a dropper bottle from AGD. Was packaged with the marker and bears the AGD logo.
