Well I burned off all the old gas (poured it in an old pot burned it off) so it sounds like I did that a bit prematurely. The good news it, I think I have figured out what kind I have. I think it is a Whisperlite. I found thier website took a look at the specs. The fuel pump assembly looks a bit different than the current model. Am I hearing you correctly that I can break down the stove parts and wash them in the dishwasher? I have no idea where the tool is that camp with the stove. There does not appear to be any gumming on the interior parts. The ball and screen are clear. If I am understanding take a knee I need to do a big time maintence on the stove. The thing that is mind blowing is I can see myself spending enough to to get this one up a running to buy a new stove altogether. ARRRRR the old fix vs replace debate.
