Hi all, ... i used to be a frequent visitor to this forum, but havent posted in a while (5 years or so).
So I dug out my QB78 last week and decided to give it a try. I had left it with 2 co2 cylinders in it for over 3 years. I wasn't surprised when it didn't have any pressure,, so I put a couple of new cylinders in and as I tightened the cap I could hear the gas escaping (not out around the cap, but somewhere internally). I assume that some of the O rings somewhere in the inner workings have dried out and or cracked. Is this something I would be able to repaired or should I send it to someone who specializes in this sort of repair? I'm fairly handy with tools and most things mechanical, but have never been into the interior of an air gun.
If it's best for me to have someone (who knows) do any of you know of any places in Nova Scotia who might be able to help me?
Suggestions...?
Wayne

Do a perusal of the mods and repair section here.

If you decide to do the work yourself, you will need a long shafted, large flat blade screw driver to loosen the valve for removal.
Both the stem seal and transfer port stock seals are very light duty material for the purpose~ in fact dis-assembly usually means replacing the port seal... The valve o-ring seal is usually sterner stuff, and very straight forward to replace...

Ok, thanks!.... I'll have a look around in the "mods and repair " section and see if I can find some info there.
I'll probably be back with a bunch of questions before this is over... :mrgreen:

Here is a good oring kit to order first before you take it apart. http://www.canadashootingsupply.ca/qb-xs-seal-kit.html
Email Raman and ask him for a letter mail code or shipping will be very expensive.
He's a great guy to deal with [emoji846]

Thanks wesb2007; that's what I was hoping for. I've been watching a few YouTube videos and think I may be able to handle the repair myself.
Not sure what you mean by asking for a "letter mail code" , but by the looks of what is included in the seal kit it shouldnt be too expensive to mail it ........... should it?

Seal kits can be stuffed in a envelope and be sent for 2.05$, where a package or bubble envelope can be anywheres from 10-13$
