I have a Campingaz Camping 206 S camping stove, like the following picture, though I'm hoping any advice I get here will apply equally well to any kind of small gas camping stove.

Campingaz Camping 206 S Stove

It's been a pretty reliable companion for heating up tins of soup or beans when I'm camping. I've started finding, though, that when I arrive on site and start trying to cook with it, I find that the burner doesn't get particularly hot - after it's been heating my mess tin on full blast for a good few minutes, the tin is still cool enough to touch, even on the bottom.

After turning it off and shaking it a little bit, I can still hear a little butane sloshing around in the canister, but after removing the canister and inserting a spare, it starts working reliably again and heats my next meal up properly. I go home afterwards, store it in a cupboard, but then find that the issue occurs again the next time I take it out a few months later.

I'm guessing that I might have a very slow leak or something, but the stove doesn't smell at all - certainly not how it smells when I actually open the valve. Is there a better way for me to check? Might I just be using it wrong?

You can check if your stove has a leak if you weigh it, together with the gas canister. Record the weight before long-term storage; check when you want to use it again.

The particular scenario (having a flame but it's not hot) is very strange. My best guess is, your gas canister contains a mixture of gases (e.g. propane + butane); the "best" gas (e.g. propane) leaks out, while the "bad" gas (e.g. butane) remains. Butane should still provide a very hot flame, but maybe its flow rate is too low on your highest throttle setting.

    The usual CampingGaz cylinders are just butane, so if using it in cold conditions that alone could be the answer to the slow burning

These burners take containers such as this one:

A gas container

They are holed when inserted into the burner and have no own valve that allows removing and closing them. I suspect that the sealing between the stove and the cylinder is not 100% tight, causing the leak if the thing is not used for some time.

Looking at cylinders from other vendors, they seem to all have a separate valve on them, probably just to avoid this problem.
