XM108HP doesnt hold gas - Need advice
 

I have a strange issue now. I reassemble it correctly (as mentioned in the other thread), but it doesn't hold gas. When I fill it, all the gas comes out through the BB holes and when I open it up again, two of the bearings have fallen out of the valve into the lower half where the spring/plunger sit.

Any ideas?

It is normal for bearings to fall out during disassembly.

It's probably not primed. After assembly, push the release valve all the way up with a screwdriver.. you should feel the bearings reset

Other possibilities are one or more warped bearing holes in the main gas valve, or damaged o-rings. Inspect them all before re-assembly.

I think it is the big o-ring problem.
