MkII S200 fill problem

[Falconhoof]

Hello forum members I've a little problem.

As in the title the rifle is a mkII S200. Its the little uns rifle and for an old knock about cheapie rifle has served exceedingly well the last couple of year with the usual pin point CZ accuracy.
I normally just refill with a stirrup pump but now when I try to pump it up the pump fills and not the rifle. Is this a known problem?
I'll try and use the dive bottle tomorrow to see if that makes any difference but I thought I'd ask now to hopefully get a bit of advice.
Cheers chaps

It sounds like a valve or fill connector is sticking or blocked and your tryout with the bottle will eliminate or prove the pump as culprit.
All I know is having a full dive bottle is a good reason to put the pump on Ebay!

Just tried filling from the dive bottle and the cylinder still refuses to accept air.
Any suggestions?

Have you tried taking the cylinder off and filling it. Rog

[TenMetrePeter]

...and another elimination question, are you using the same fill pipe and adaptor or another one?
If using the same one, does it pass air freely before connecting to the gun?

Different hose on the lump and the bottle.

I've just removed the cylinder from the rifle to no avail. I also tried knocking the nipple with a plastic handle from a screwdriver to see if that loosened it. Hmmmmmm

I take it that this is an old style filler i.e. Push on type, if there is no air in the cylinder, you should be able to push the centre pip in with your thumbnail, is that possible? If you can, and there is no air! Unscrew it, and have a look inside, there is not a lot in there to stop airflow. Rog

Are you sure it's not full.have you fired it.

[Falconhoof]

There's air in the rifle as I I was using it then when I went for a refill the problem arose so it isn't full.

try this-- cock the rifle and leave it cocked then try too fill it, this is normaly for when its run out of air altogether but its worth a try. ////// the other thing too try is remove the cylinder from the rifle then try too fill it, when connected too the air bottle open the fill valve quickly,, but be carefull only just one short burst.
