    Been trying to get this to work and after much changing of bits.......it lights like a good un, you can hear the jet hiss as you open the valve....for about 10-20 sec and then floods paraffin out of the jet and I cannot get it back to a stream of gas.Same every time.
    Is it the nipple jet ? Which seems to be bigger than those on other stoves ?
    If so, where do I find one ?
    Thanks for any ideas, am out of them myself.

    Others use Aspen or Panel Wipe of the correct type.

    I can't say what is in the gasoline in Ireland, [or more importantly --NOT-- in it], but in the US, auto gas has too many additives that are great for performance in an internal combustion machine, but will gum up the insides in a gas pressure appliance, and may even produce harmful fumes for humans.
    Coleman fuel has no automotive performance additives. It doe have rust inhibitors, and will stay shelf stable for a long time.
    Automotive fuel does not have any stabilizers and will gum up in the fuel tank and carburetor, and go bad stored in a jerry can, unless a stabilizer is added.
    I bought a gallon [3.8L] of Coleman gas last week for $14.50. I bought a gallon of denatured alcohol camp fuel the week before and it was over $20.
