    :(

    When installing a new jet in the burner head which I had just cleaned (heat/quench) of my Radius 21 (same as Primus 210), I tightened it too hard and stripped of the top of the jet. So now I'm stuck ... I installed the jet with some copper grease on the threads so it went in pretty smoothly, but probably just to far and the wide (top) part of the jet sheared of when it couldn't get beyond the threads.

    Is there any way to get the rest out of it? I know of these reverse bits to drill out screws, but how do I get something in there, and then get some leverage on it?

    Any help is welcome...

    Thanks,
    Ted

    YES - got it out - read through the forums and and decided to make a Torx 10 bit so that it fitted the joint key - took almost 1 hour with a dremel - pressed the Torx 10 into the stripped jet and slowly got it out.

    Looks like a roarer for a start so difficult! Try a screw driver of an appropriate size with the flat bent at 90 degrees to the shaft and wedge it in the remains of the jet and turn it. If as you say the jet went in smoothly with grease it may come out to the point where you can get a pair of pointed pliers or the like on the remains of the jet and turn it out.

    It would be a lot easier of course if it was a silent burner. Just an idea!

    Edit - Just seen you did it very elegantly well done!

    They sell easy outs for things like this. Good thing to have in the tool box.

    Replace all washers, leathers, gaskets etc incl the pip in the NRV and its burning in the first try without any lightening issues.

    Once I get more kerosene I'll put it side to side with the Primus 210, but for now I see the flames are much better looking, no flaring or yellow tips, all nice and blue ... But it also looks less powerful, a liter took almost 10 minutes to boil. Perhaps it was because I had only a small amount of kerosene left (200ml). Also, the tank was quite warm, too hot too handle, after a 1/2 hour run.

    I was under the impression that the jet aperture is somewhat smaller then the 210, I can only get a pricker in that measures .27 on my micrometer, and I cannot get a .32 pricker in it.

    And, I feel less resistance during pumping. Pumping goes OK, the NRV does not leak, the pump stays in position but it just feels different from the 210.

    Anything else to check or is it fine as it is?

    Thanks,
    Ted

    And it runs fine now ... had a large piece of sand on the filler cap gasket and that's where it leaked a little pressure (noticed that after submersion it in water). Now the stove boils a liter in less then 6 minutes. Still yellow tips but perhaps it's the fuel I'm using. Anyway, I'm happy how it performs.

    Here are the requested flame shots and a video
