220F Muffled Sound on Ignition

#1

Post by burnt bacon »

Evening, Gents. I tried starting a 220F, 03 '70 for the first time. It's in nice shape. Valve operates well and with 1/4 turn, I hear the fuel pretty quickly. It also ignites promptly, except it makes a fairly loud muffled sound in addition to the hiss. This sound goes on for about 2-3 min, then goes away. It burns bright, but continues with a pulsating mode. Now my second pulsator, unfortunately... :(

Any ideas as to the cause fo the sound? I guess my next question is, do you tolerate a pulsator, or take it apart and rectify it? In my limited experience, it seems to burn fine but for the pulsating.

Thanks...

I personally find a pulsing light quite annoying. I want a lantern to burn steady as a light bulb. I rebuild my generators and use bronze wool. If I get pulsing, I remove the generator and just add a little more bronze wool which resolves the pulsing.

I suspect both of your issues are with the generator. I'm not sure about a muffled loud sound, but I suggest loosening the generator and turn it several degrees and tighten the nut up again. Sometimes the tip wire will vibrate and create unwanted noise. Hey, it's worth a shot.

Disassembled the gen and near the top, around the outside, the brass is deformed. Trying to peer inside of it I couldn't see any deformity. Cleaned everything, re-assembled, then saw copious leaking from the nut. Untightened, re-tightened a few times and the leaking was still there, another mystery I guess.

I'll order a few generators...see what happens with a new part.

Inspect the flare of the gen and look for a crack. If none, heat it up real good, let it cool and reinstall it to see if that stops the leak. It may just be a bit deformed. You probably don't need to let it cool other than to not burn yourself reinstalling it. :) Also make certain the generator nut hasn't got a crack. It's not common, but can happen.

Thanks, Jim. I just re-installed and now it's not leaking, but will def keep that tip in mind.

FWIW, here is what the deformed portion of the top of the gen tube looks like...

Check your burner tubes also make sure they're not loose same with the caps

Thanks, Shawn.

I tried running it without mantles, and saw the source of the muffling sound in action. It's the sound of the vapor shooting from the burners, while it is literally blowing out the flame. Tried it twice, and both times after lighting the burners blew out the flame. I think the gen is to blame.

That deformity just looks like excess solder running down the gen. By that, I don't mean the low temp solder. I've melted it once when using a torch to heat a gen to red hot for a heat and quench. Fortunately, I didn't lose the seal, but now stay away from the tip.

>>Tried it twice, and both times after lighting the burners blew out the flame. I think the gen is to blame.

If you pumped it up like you would with mantles installed, this is to be expected. Without mantles, you only want a few pumps, maybe as much as five. Plus, you should use a torch to continue heating the generator since there are no mantles to do the job.

Leak at genny base.....nut has to be tighter than you think in many cases. Glad you got it stopped.

And without mantles, is easy for flame to blow themselves out. Low pressure, good pre-heat, and open valve fully will help keep it goin. Don't blame the genny.

Though I don't like that solder on the generator. Since I have a lot of 220 gens, I would not use that one. If it splits, you are gonna have a real hot mess on your hands.

It does look like solder, but where is it coming from? It causes the tube to bind a little bit when removing and replacing.

Thanks, I didn't know that. But, the sound was identical to the problem sound from before, so something similar is going on with the mantles installed. I'll try attaching two more and see the outcome.

Every lantern has a personality. If the muffled ripping noise goes away once it's warmed up I wouldn't worry about it. (Some 288s are known to howl like a banshee, I have one.) The pulsing could be a generator issue, or it could be a fuel-air tube issue. No way to tell without swapping the generator for a known good one from another running lantern. Or, taking the whole lantern apart to get to the FA tube and check it.

The sound you are hearing is in the air intake. I've got a few that do that and one of my brothers old ones that absolutely howls. Once warm the stop. One of them had a hum that was at a frequency that drove me bat 💩 nuts so I dove into what was causing it. I had to file off the end of the screw that sticks in the base of the burner frame. It's all about velocity and being cold. Once things warm up the dimensions change and it goes away. Most of the time there's something you can do to stop it. Had a guy bring me a late model power house with a howl. I used a de buring tool to remove the lip in the ID of the burner frame inlet. Didn't make a peep after that

I never thought that little screw in the air tube could cause noise. Now i know anther place to look.

I was going to video my howler today but didn't get to it. Maybe next week. It's a 295 and howls so loud it vibrates the globe. Lol It's kinda funny so I've left it alone. I've found this more common on the pressed metal air frames.

Maybe they're crying because their brothers and sisters have been sent to Etsy, where lanterns and lamps go to die a horrific death.
