Level 10 tuning

[FlawleZ]

Here's a LV10 problem for you guys:

OK, I've got a Classic RT that I've already tuned a LV 10 perfectly for so I'm halfway experienced to say the least. I just got through building a classic PF mag from the ground up (nothing special, just a good backup gun). Anyway, I got a used LV 10 with the valve and pretty much everything came with it. I started with the standard 2.5 carrier that everyone starts on but it was too loose. So I went down to the 1.5. Too loose. I'm on the 0 size carrier and it fits "ok." It won't slide off if I hold the bolt upside down. I'm using 2 shims currently and it STILL LEAKS. It leaks down the barrel as if the carrier was too big. I've checked the shims and they are ok (no serious bends, creases). The rings are fine and all are oiled. Marker shoots fine just leaks a bit down the barrel. It does stop when I hold the trigger down. I've already tried backing out my velocity screw to relieve some pressure but it doesn't seem to help. I've fired approx 75-100 shots and the gun still leaks. I'm wondering what I could be doing wrong? Everything is installed as should be and I'm on the smallest carrrier.

Any input, ideas are welcome. Thanks guys.

I don't guess anyone else has anymore ideas on what else the problem could be?

did you ever try replacing the power tube o-ring? also dose the bolt stem have any visible dmg to it or dose it look alright?

Checked and re oiled the Power Tube O-ring. Still leaked. I got to thinking and I took it completely apart again and turned towards the LV 10 once more. I was checking for the seal around the bolt stem and the carrier and it was a bit loose to me. I changed the ring on the carrier to a newer ring and that solved the problem! I'm still on the #0 carrier but SHE'S NOT LEAKING so I'm leaving it at that.

Thanks for all the input guys.
