Petromax 821 / 250CP Maintenance 

Hi Adrian, another excellent tutorial. I bought this exact same lamp 35yrs ago, as a night fishing light. It's still going strong, annual o ring and nozzle pricker changes, decarburizing, and as required mantle replacements are all that's needed to keep it running sweetly. Mine is so bright, it's impossible to look at without being blinded for minutes. I've added highly polished chrome plated shutters to protect the glass and also direct the light. Here in the U.K., parts are still easily obtainable Thanks again. Stuart

Great video

Thank you for another very interesting video. Very happy the lantern is working great again.

Great stuff Adrian, especially making the knob! I've got two of these, I'm glad that parts are still so widely available.

Usually, I shut them pressure lamps down by releasing pressure from the fuel vessel. That reduces the smell significantly

Great job

Very informative and useful video, thank you very much!

Sehr schön! Das ist ja schon eine tolle Technik.

thank you Adrian , for sharing

Sehr informativ, Danke.

It's good to see that you're still making old things working again, Adrian. Keep up the good work! I remember reading a few of your short stories a long time ago, is there something happening as well or are you now solely into mechanics?

Hi, abschalten tut man aber immer mit der Druckablassschraube am Manometer! Wenn du mit dem Vergaserventil abschaltest, ist der vergaser noch gefüllt mit Petroleum und braucht ewig bis er leer ist und abkühlt und kein Gas mehr rausströmt. Während dieser langen zeit schaut die nadel bei der Düse raus und du hast einen sehr hohen nadel verbrauch oder kannst auch nadel und vergaser riskieren dass die zusammen verschweißen. Deshalb druck ablassen, und die lampe geht instant aus und das petroleum läuft aus dem Vergasergestänge nach unten und die nadel und düse sind safe! lg

I have a problem I hope you will take the time to review: I bought a Wenzel Petromax clone. It got clogged. I removed the generator, and the rod inside it. After replacing the tip, I cannot get the rod to "catch" on the throttle, so it won't go up and down (making the wire tip go in and out of the little tiny aperture), so I cannot use it. Any ideas how to get the internal rod to "catch?"

Super video! I just took delivery of an old Petromax 829 today Sehr informativ, danker. Your turning of the brass knob was fantastic! Also this is the first time I have seen demonstration of the replacing lead washer/seal. Did you clean carbon from the control rod and inside the generator tube?

At 7.40 you mention graphite yarn, where do you get it?

I had one petromax, but it is missing all superior parts, the glass, and i believe that i must do what you did in the burner. Could you help me? Where did you buy the parts? In time, I in Brazil. Thanks in advance.

Is the fuel gasoline or lamp oil? I prefer the petromax design over the US made Coleman. 31 45B

Hello, great video and job. Could you tell me the dimension of the globe because I can buy the same baby 821 but with no globe, I can't find the answer. Thank you very much :)

Auch ne Dichtigkeitsprüfung Durchgeführt?

For turning it off why mot turn it off and depressive it?
