    I took my Sea 123 camping this weekend and it burned horribly. The flame was high and yellow and it sputtered. When I turned it off, it remained lit so I had to blow it out.

    I picked up this Sea last fall and have since disassembled it, cleaned it, replaced the with with a cotton mop string and I am using Coleman camp fuel.

    Any insight on how to get it to burn clean?

    @Rob Carignan Underprimed? - yellow flame, residual unvapourised (wet) fuel remaing lit when regulator spindle closed.

    Hmmm. Perhaps I'm not priming properly? I warmed the reservoir with my hands and when I open the kindle fuel came out.

    @Rob Carignan The concept’s ok (though I use alcohol for a cleaner prime) but you need to shield the stove from draughts - the built-in windshield isn’t always enough. The primer cup should be as full as you can get it without it spilling over.

    In cool weather I always double prime; it often is needed.

    Well, I primed and the fuel came up very quickly. Big yellow flame and sputtered. I'm having trouble posting a video.

    Well, it surely points to a shortfall in full vapourisation. With respect to your skills in replacing the wick, the ‘fit’ of the wick in the burner riser can make a difference. Too slack and fuel will pass to the jet too rapidly, losing out on vapourisation.

    +1 on Johns remarks concerning the wick - but even the smallest fragtment can clog the jet - especially after fettling the wick when small pieces can be turned loose, so I would prick the jet next time it sputters, just to be sure.
    A piece of glassfiber string or Carbon felt in the little priming cup will give you a much better preheat even in colder weather.

    Thanks, I'll drain the fuel and check the wick.

    Hey, I think I figured it out. The nipple or jet wasn't screwed down tight and fuel was seeping up through the threads. It seems to be burning correctly.

    I spoke too soon! It works great BUT the spindle is off track and I couldn't shut it off. I blew it out and put it out in the cold to cool and depressurize.

    Thanks. I broke the needle last night. That's why it wouldn't shut off. Drag.
