Hi Guys, picked up a 275a over the weekend.....its from 1979.......cant get it to light unless i invert it......then when upright it dies out.....so i broke it down.....cleaned up fuel tube, new schrader valve.....still doing it......noticed  the solder joint at top of fuel tube isnt tight, i get air, carb cleaner out of joint when cleaning it......from what ive read on the late model 275’s the fuel/air mixture is regulated at the nozzle on bottom of tube......so im thinking i need to resolder joint.......pic attached has arrow where i suspect bad joint......any input on this issue is appreciated......thx

Nice looking turd 💩 (this is the only place you can say that) Sounds  like your air pressure is going out that bad joint and not taking any fuel with it. My 530 stove had a similar problem the inside tube was floating free letting the air out that way. I don’t know enough about the 275 F/A tube to say about soldering the joint. But I bet a new tube will fix it

Is there by any chance a lengthwise crack in that F/A tube?

"noticed  the solder joint at top of fuel tube isnt tight, i get air,"

That is probably supposed to be there. The lantern operates on the same principal as the older lanterns in that there is an air gap/inlet at the top of the outside fuel pickup tube. Seeing that the fuel pickup tube is brass, I've included a link to the patent pdf (too large to post) that should be for that type lantern so you can see how the fuel pickup system is designed.

there doesnt appear to be any crack lengthwise in tube.....that crimped/soldered joint at top of tube has failed......i installed some shrink tube & tested it, appears to be the culprit.....so now im thinking resolder?C26DDFC2-1640-4F4B-8312-937DABE17240.jpeg

Don't expect the heat shrink tubing to hold up as I don't think it's normally fuel rated.  A member here tried that some months ago, but it swelled and fell off.

Hopefully someone comes along to confirm what you found with your tube.  There should be a way for air to get in there on startup, like zoomkat posted, but I've not pulled a 275 apart to investigate that.

shrink tube was to just confirm my suspension that somethings going on at top of fuel tube.....which it did......now this model doesnt have the F/A metering rod below schrader like thr earlier valve on a 275......from what ive read the bottom orfice is doing both air & fuel.....if i understand things right

Some of these newer lanterns run on magic, or at least seem to.  🙂

I don't think you want to conjure up satan for a lantern or anything else in your life.

Some, well most of the new adjustables, light up for me with no drama what-so-ever, but occasionally, one wants to flame up first.  I never investigated these enough to understand the differences.  

When it comes to the 275, I've always despised the ugly brown color and never wanted anything to do with one.  Then I found one with the fluted glass and picket fence, so by default, that one is a keeper.  Then I picked one up for parts to give to a friend.   And this danged thing in the easiest, smoothest lantern to light.  I hate that these are breaking my resistance.   My friend got the parts, but in a swap.  He'll likely end up with this whole lantern, but just not yet.

The patent for the fuel pickup tube with out a fuel control rod was not granted until 1985, and I would think is the current design used. Below are some pictures from that patent showing that they are somewhat different from the earlier one knob design. Does your fuel pickup tube have a hole in the bottom? Bottom line, from what I've seen, all reasonably recent Coleman gas lanterns have air inlet ports at the top of the fuel pickup tube.
