izh question:

Yesterday, I change the main seal successfully.
It was difficult to remove the old seal and put a new back into the cylindrical piece of aluminum recipient.

That piece of cylindrical aluminum has a thread, I think that if I loosened the thread would give a little more pressure (and more power) when loading the gun.

It's posible?

Probably not a good idea, having threads that are not tightened.

What would be the benefit of that extra power?

Nano, is your IZH the standard or "M" version? What makes the "M" version have more velocity is the longer compression cylinder that allows more swept volume from the piston. Are you using the Izzy to compete or you want more power for informal plinking?

If you adjust it tighter, you won't be able to close the charging lever. It should already be adjusted to it's optimal distance.
