Baikal izh-46 problem

[kneal]

I've just treated myself to one of these, and very nice it is too ... BUT at least half the time the action of closing the breech vents all the air from the chamber.
There would seem to be nothing wrong with the two breech seals, once the breech is actually closed the gun is fine.
Anyone else come across this problem, and any ideas of a solution? Thanks in advance for replies.

Is the trigger pull adjustment set too light ? Try setting it slightly heavier.

First stage pull or second stage? I have not adjusted the trigger at all - it still has its factory settings (and seems about right for me).

first pull or second pull? I haven't changed the factory settings - which seem about correct for me.

Are you sure that at the forward end of the cocking stroke, when opening the pump lever, you are pulling it all the way forward so that the breech lever (which lifts to expose the breech, carrying the transfer port with the two seals on it) is vertical?

That is to say, is the trigger mechanism and valve 'set' before you start the compression stroke of the pump lever?

I actually used mine for quite a while before realising that opening the pump lever did more than just release (and open a little) the breech lever, which I was then pulling back by hand as a completely separate action.

There's also this article primarily on dismantling, but which mentions a problem developing with the valve seal, would that be worth looking at and re-lubing?

Pellgunoil isn't something I've ever used, Ballistol should be ok on seals I imagine but since there's also the metal valve stem to consider I use Bisley Gun Lubricant on mine (Abbey SM50 is similar, I think, but I've not tried that yet).

It's not a problem I've ever had on mine, in fact I've never had a breech seal blow out either which is something else that's usually mentioned to look out for (well, except when I deliberately left the breech open slightly after reading of this to see what happened).

Definitely cocking this as far as it will go - breech is vertical - and anyway the cocking action is the same for all shots, even though only some result in leaking air. This is very much an intermittent fault within the gun's mechanism.

In the circumstances I've decided to send it back for rectification. I really don't feel competent in dismantling it myself unless it had turned out to be a straightforward fix.

Cheers for all the advice - I'd still be interested in any other thoughts or comments on the problem.

Let us know the results - I am interested in getting a target pistol and the IZH was on my possible list.
