how many shims and what carrier are you using????

[blakdragon21]

I just got an x-valve. I got the smallest carrier in it right now. I have the carrier with nothing on it and I only have one shim. If I had more shims it will leak. With the set up i have no it gets little reactivey and no sweetspot.

Which carrier are you running and how many shims? And why? How does your marker shoot with that setup?

You don't want to run the zero carrier initially. The oring wears in and starts to leak. By being on the tightest carrier, you don't have anything to go down to.

Carrier/shim wise- it varies from gun to gun.
