Two Burner Stove

It may be blocked jets. Take the burners off and the jets are weeny little brass things that you unscrew. Blow them out with a compressor and refit.

Worth trying before buying a new lead.

Hi John,

Have had the same problem withe a jackaroo now do it up using a pair of pliers this helps compress the centre valve allowing the gas to flow.

John,

Did both burners fail at exactly the same time? If not, I don't think the problem can be attributed to the gas line. If they did, could be the line, but the most common fault we've experienced with the 2 burner Jackaroo is blocked jets. A dirty batch of "gas" (it's actually liquid in the bottle), and if some liquid gets into the lines, any goop in it blocks up the jets. These jets contain a porous layer which controls gas flow rate and keeps particles from reaching the jet proper, but seems to me it very rapidly gets choked if any liquid gets near it.

As Jim says, you could try removing the jets (they are screwed into the back of the taps) and cleaning with compressed air but I've had very little success with that approach. Cleaning by soaking in petrol rarely works.

Suggest as a first step, buy a couple of replacement jets from a camping shop - (note the letter stamped on the present ones, probably "k", and get the same types. That letter defines the size of the jet.) Replace them and you probably have a fix.

I've found a good preventative measure seems to be to bleed the stove whenever you finish using it (ie turn off gas off at the bottle and then at the knobs). We used to turn it off at the stove and then at the bottle and found the stove started flaring up etc (different brand to yours) which probably indicated blocked jets etc. Once we started doing it the other way around we had no problems using a 2 burner stove when we were living in a shed for a year!

We had a similar problem last year, with a Gasmate stove (not sure how similar they are to the Jackaroos). Anyway, the valve in the stove was stuffed. It turned out to be a Schraeder valve (ie. car tyre valve), and the rubber had deteriorated after years of faithful service, and was jamming the valve in the closed position. So took a Schraeder valve from our box of spare parts, screwed the new one in, and hot coffee was back on the menu. Woohoo!!

Thanks for your posts folks. V. helpful.

Our 3 burner Primus started flaring and sputtering after a gas refill at a remote roadhouse; then two burners pretty much choked off.

I've pulled the jets out and crikey they're fine. I have a manual pricker from a shellite hiking stove and that's too thick.

In case it's of use to others, the jet no. on the small middle burner is 18 and the larger burner is #20

Cheers.
