Butane noobie here... I just got this stove (for free!) but I'm having trouble with it. It's a Taiwanese Athena pocket butane stove and it has it's own internal doughnut-shaped tank that you fill with a butane cartridge. I think my problem is it's not filling correctly. You press the cartridge needle into a port for 30 seconds or so, and the cartridge fills up the tank. Problem is, I might be missing something from the port. The needle doesn't seal very well, and a lot of butane leaks out when you press the cartridge in. The port has internal threads, so I'm wondering if there's a part that's missing? This is what the internals of the stove look like: I get a flame, but even after filling for 30 seconds, it doesn't last very long, so I suspect there's not a lot of fuel in the tank. Anybody have any suggestions? Normally I stick to white gas, so I'm kinda clueless.
