just picked up a 220k lantern in decent looking shape, holds pressure and all. When cracking the valve an 1/8th turn to light mantles, fuel begins to pour out the mantles filling bottom of globe. If I turn off for about a minute that seems to be enough for it to warm up and the mantles light like they should.  But I have no adjustment,  its all the way high or off. Any ideas?

Hey Alan, welcome to the forum.  One of the best ways to find a solution to your problem is to learn the basic terminology used here and hit the search feature.  I just did a search for ‘220k flooding’ and found a couple of old topics about the exact problem you’re having.  In that research it looks like the flooding can be caused by something as simple as loose generator tip or as complex as a cracked or dirty fuel air tube in the fount.  Here’s a short list of things to do from easiest to full on wrenching.  I’m sure there are other things I’m not thinking of.  And always be careful as you’re playing with fire here.

  1. check gen for loose tip
  2. clean generator
  3. confirm the right gen is installed on the lantern, not sure how you do this without just replacing it with a known correct gen
  4. pull the frame and make sure the airways are all clear
  5. Drain the fuel from the fount and fill it with some kind of liquid carb cleaner (not the spray kind) and let it soak for awhile, empty and flush with fresh cf.
  6. pull the valve out of the fount and clean or replace the f/a tube manually.

Here's you some good reading material. By the way the 220K is non adjustable..

Flooding can easily be due to just inexperience in starting "1/4 turn open" to start lantern. The starting sequence is fairly simple, so be sure to follow it. Only opening the valve 1/8 turn open when 1/4 turn open is recomended may result in a flooded condition. The valve position is important for suppling the correct mix of air and fuel into the generator.

Yeah, the link In Toby’s post is what I was looking for.

Thanks for the quick info, I tried an 1/8th turn cause 1/4 would flood it baddd

One thing to try is to crack the valve just a bit to get a little fuel in the mantles and turn the valve off, then light.  Then when the gen has warmed up and the mantles are burning white, turn the valve back on.

This isn’t actually fixing the flooding problem, it’s just learning to live with it.  

If you start digging into it let us know what you find, that way we all learn something.

Sometimes short of a new F/A tube is the only way. Stretching the spring helps but in my experience doesn't always fix.

In the past somebody may have removed the fuel control rod and not put it back in, or maybe did something else to the lantern. Typically unmodified lanterns will exhibit fuel starvation instead of flooding with everything else being equal. Just saying I think flooding is most likely the result of the startup procedure used.

That's not how the valve works.  That 1/8th turn difference will not have a negative impact unless 1/8th is not enough to even start fuel and air flow.

The pictures of the cut-aways in the post linked below from nfadude explain a lot.  On a properly functioning lantern, the valve must to be open quite a bit to stop the air mixture and deliver straight fuel.  Unfortunately, PhotoBucket still has their watermarks on the pictures.

Flammable liquids, open flame, what could go wrong?


I've missed you!  But I'm reloading.

I know quite well how the fuel valve and the fuel pickup assembly works. If the fuel valve is only opened a little so there is lower flow thru the fuel valve. then the leak by at the fuel tube orifice might be able to keep the fuel pickup tube flooded. This would allow only fuel to be supplied to the generator.
