When I fill it, it sprays a whole bunch of gas out from the valve area. edit: it's also not getting a full fill.
And when I pull the pin, it will go out half way and then get stuck- really, really, really stuck.
Ideas? Am I doing something wrong? Anything I can do without taking it apart? I can't find a hex key that fits the screws yet.
I got one good throw out of it, at least.

Pretty awesome.
