I have read where soaking a F/A tube and generators in vinegar will dissolve any fuel deposits and gunk to clean out the inside of the F/A tube.
I have a 200A that is being an A Hole and will not start or run smooth like the others.
I have cleaned the F/A tube multiple times with spray carb cleaner and compressed air and even put on a new generator.
It still starts rough and you can hear it pulse a bit when running. I read where vinegar soak will dissolve the old fuel gunk in the F/A tube.
Will Citric acid do the same ??

I have a similar issue happening with a 502 stove.  I learned I may need clean out the check valve at the bottom of the tank where the air is pumped.  I've replaced everything else.  you may look at that as well.  Good luck.

those types of acids dont effect fuel and fuel residue well. more for rust. I use a torch tip cleaner. The long cleaning rods will fit up into the FA and physically remove it with a bit of scrubbing. dont over do the bottom hole, or it will run rich on startup. Sparay carb cleaners are not what they used to be. Seem a waste of cash to me. JMO.

I am thinking that there may be a bit of gunk in the Quick start circuit. It takes a long time to get a fuel gurgle at 1/4ish turn on the valve. 30 plus seconds at times.  When it does it is irregular and causes it to light difficult. Once I get it lit the lantern will run strong with the valve open. I can hear it pulse a bit when it is running wide open. Not enough to see in the light, just enough to hear when I stand next to it..

It has to be something in the quick start circuit of the F/A tube......

I just run the rod both ways through the FA tube when I have it apart. Never had anything stay in there afterwards. Have you tried a different generator, just to rule out if there's anything in there that may be inhibiting fuel flow?

And the F/A rod has a spring attached. I usually stretch mine a quarter inch or so (10mm). Some don't see a value in this but I do.

How do you guys get a rod to go through the INNER space on the FA tube? Thats the place thats usually the problem.

I give 'em a soak in the citric acid, then blow air down from the top while leaving the side hole(s) open. I usually get a blast of green schmoo out of 'em. They work lots better after that...

Like Kurt said! I also slide a tiny tip cleaner in and out of all the holes. Always works.
Due to budgetary constraints the light at the end of the tunnel has been turned off.
Thank You

Kurt, When you say soak in citric acid, just what do you mean.

I did about 15 min in a mix of 2 tablespoons to 1 gallon of hot tap water.
I pulled the F/A tubes and all the other brass parts out when they started to turn color.
I gave them all a blast of air and ran a wire thru the tube where ever I could get it to fit..
Have not tested it yet, maybe tonight I will get some time..

Oh yeah, I put my lips on both ends and the side hole(s) and blow it all out...

I use more citric acid but the exact proportions aren't that important. I let it soak for maybe half an hour but thats also not a critical thing, I've forgotten parts overnight before, it doesn't ruin them.

The thing to remember when blowing out the FA tube is that there are 3 holes and if you just shoot air through one of them will get ignored, the straight through passage is the path of least resistance.

In the 200A video I ran the FA tube through the ultrasonic cleaner, it accomplishes the same results, mine doesn't make it look as good but it gets as clean:




Edit: The video is supposed to start at 4:09 but it doesn't seem to have worked, skip to 4:09 to see the FA tube cleaning.

Loved the Youtube Curt.  Thanks for putting that together.  I did not have citric acid, (I do now)  I used vinegar on an 220K F/A tube that was totally tarred up all the way around.  I used my thumbnail to scrape chunks off and realized just how deep this stuff went and then went the vinegar route.  100% vinegar in a tube just big enough to hold the F/A tube and let it soak for about 15 minutes.  brass brush on the outside and emery clothed the rod and ran it through both directions.  Then rinsed in HOT Soapy water and then plain water before blowing it out with the compressor through all holes like the video shows.  The vinegar worked to take off the tarring inside and out.  Put a new generator on it and it's now running like a striped bottomed ape.

I appreciate all the experience shared on this thread.  Helped me out a lot and is a great reason to be in this group.  

Thanks again for all the input and especially the videos,

Hercel
