    I've not long had this rough example of an Enders Baby and having changed the seals and pump cup washer I thought I'd got away with not having to replace the wick, since it ran fine for a while

    Alas, the flow of fuel through a tired old wick, run dry and burnt at some point (I subsequently discovered on inspection) must have begun to dislodge the caked carbon and too frequent pricking of the jet was the first symptom. Removing the jet disclosed an accumulation of carbon chips. The wick had to come out

    Here it is

    It didn't come out before the burner feed pipe nut put up a fight, ending in a knock-out (it rather than me fortunately).

    On closer inspection before I got to work on the nut I could see that it was a distorted (flattened) hexagon and pretty chewed up. Someone had tried to remove it (prompted by the worn-out wick no doubt) and failed, doing a better job as a salesman.

    I removed it with a stillson wrench in the end, and silbrazed a decent-sized steel nut over the old brass fitting - something I could get a spanner on in future (should I have to) - with a better prospect of removing the pipe from the fuel tank. On the burner side of the nut I built up a fillet of silbraze for no other reason than I was silbraze-happy at that point and me and the filler metal went with the flow, as it were

    That job done, back to replacing the wick

    Test firing. Happy with that

    Thanks Trevor.

    I wish anyone attempting the removal of that pipe to replace the wick better luck.

    If the original nut hadn't been in such poor condition I'd have made more effort to get the job done without the surgery, which was a last resort to retrieve the stove.

    Sir does the iron rod that attached to the wick should be entirely inserted in the tube?
    Thanks

    The wire should be long enough to leave a bit exposed to grip when(if) the wick has to be replaced again in the future. It’s good practice to insert the wick as far as it will go in the inlet tube to maximise vapourisation.

    @kerophile Thanks for the alert.

    @Ouss The purpose of the wick is to deliver vapourised fuel which it must be doing efficiently for you to report as you have.

    Priming issue as you suggest because you’re shutting the valve during priming.

    It should be shut before priming, then opened when the priming fluid has burned up (you then need to use a lighter to ignite the burner), or opened just before it’s burned out to enable the priming flame to ignite the vapourised fuel.

    I doing so as you mentioned.
    My problem is:
    i got vaporised fuel with small leaking through the nipple hole.
    Maybe due incomplete time to prime?

    @Ouss You can soon check that. Prime a second time directly after the first. Make sure too that the stove is windshielded to prevent the priming flame being diverted from heating the burner. Quite a light breeze can do that.
