It's a beautiful, brass-colored stove, apparently barely used, that I bought on eBay from a previous owner who said he pulled it from a sailboat. I'm restoring a 1972 MacGregor Venture 2-24 and want to use it in the galley next summer. I've tried to fire it up using denatured alcohol fuel, but it appears the washer does not seal. Pumping affords no resistance at all. It feels as though the pump shaft rattles around loose in the tube. Perhaps the NRV is no good as well. The seal on the fill cap on the pressure tank appears to be solid, although it is slightly grooved. I've researched multiple very informative articles here on CCS after searching on "Homestrand." I also found Twoberth's recent post on Finding and Fixing A Leak, which seems to set up a well thought out batting order of trouble shooting. But is there anything peculiar to Homestrand models not covered by Twoberth? In the morning, I'm going to grease the washer on the pump shaft as someone here recommended and see if that helps, but it appears the pump washer that is on there is not cup shaped, but more like a flat band. There also seems to be a lot of wiggle to the washer assembly, which is not tight to the shaft. See photos. I also can't tell whether the filler cap to the tank, which I understand also has a pressure release function, works. Is there way to test the NRV before replacing it, or test the pressure release on the tank filler cap? I saw from various postings that Ess Kay Yards at one time carried parts for marine stoves like mine, and Base-Camp was also recommended. Does that still hold for a Homestrand Mariner? My guess right now is to replace the pump washer. I'm a complete newbie to this so any help would be appreciated. Thanks.
