A point to keep in mind -- the smell will hang around after the gas leaves. It's very potent stuff indeed. A weak solution of dish detergent in water is your friend. You want it so that bubbles will stick around for a bit, but not so much that you get suds. Slop it around with a basting brush or similar and look for little growing piles of bubbles. As someone said, the main suspects are the bottom of the tank underneath the tack-welded certification tag which traps water (design flaw), and the rectangular Marshall Brass 260 regulator. If the tank and all the connections test clean, including the connections from the regulator to the plumbing that goes inside, then you can assume it's the regulator diaphragm leaking (design flaw; they no longer make the rectangular ones). The Marshall Brass 290 is the replacement; if you can't source it locally Frank Condelli sells it on his website. It's a screw-in replacement except that it's an inch or so longer; so the outlet connection will have to move back. On my '84 I was able to hand-bend the tubes to get enough space -- they started to flatten a little but not enough to matter. Others have replaced that section with new tubes. Yours, David |
