Hi, I picked up a 1322 last week from the forum. All seems to function fine, if a little low on 'umph'. I have run it over the chrono with AA fields (only .22's I have at the moment) and get no more than 3 ft lb. In fact 7, 8, 9, and 10 pumps all produce about the same power.
Is this normal for one of these? I was expecting more grunt per pump, with 10 pumps producing around 5ftlb.
It was made in March 1993, if that helps.
thanks Mike.

definately something wrong with it bud, mines about a 1999 model, 3flbs at 10 pumps....not right, mine does nearly that with 3 pumps. sorry dont no enough about these to offer a solution to your problem, just learning about them myself.
It should make more than that, have you oiled the piston with an appropriate oil?
An off the shelf transfer port from a tuner may sort it out if yours is an under size item,

The only things to watch for when stripping one are
The safety spring & ball which will fall out of the top of the grip frame when you remove it if you let them
and
The valve comes out & goes back in the front
and
The rear sight screw is the top screw retaining the rear tube plug.
Beyond that it's such simple screwdriver work I can't see you having a problem, grips off, front pivot out, piston & pump arm off, rearsight off, breech off, barrel off, grip frame off, plug & hammer out the back, valve block out the front.

Ok, so that's it apart. I now need to know what I'm looking for to improve/restore power.
The pistol is at work at the mo. I will bring it home later, and strip it tonight. The good lady is away this evening, so a little grease on the kitchen table won't be a problem.
Have a good look at the valve stem, if it is ground square as opposed to round yours is an official detuned uk version. I had the same, made around 98, and it never exceeded 3 ft lbs, half the air escapes the air reservoir via the flats of the valve stem and not getting into the transfer port.

...... or the transfer port comes out and you never see it again after dropping it onto your lap (even though you and your wife spend 1/2 hour looking everywhere for it, hoover everything up and go through the bag with a fine tooth comb) and you have to order a new one. No doubt I will find it in 2 months time when I least expect it, which is what happens at work when a spring or clip flies off and I spend an hour crawling over the workshop floor looking for it.
