    Opening the poppet retainer was by far the biggest challenge. I found a 6 in 1 MIG tool that had perfectly sized section in the jaws to grip the retainer. The teeth were filed down with chainsaw file. After a weeks soak in WD40, it opened right up using thin blade small adjustable wrench to turn the stop while gripping the retainer with the MIG tool. Thanks to @Luis H for sharing repair procedures showing correct tool and @rsingler for the WD40 idea.

    Here is another Tony Christiansen creation from the early 80's, a Seapro Zepher. It is in very good condition, I have not yet tried to open the pilot valve, shown on lower right

    I had noticed you picked one up a few years ago, and defiantly would enjoy hearing how it goes if you find time to check it out.
    Mine performs decently, but I think not to its full potential. It has been a year since I last played with it, and now have a few new tuning and adjustment ideas to test out.
