Honestly no real clue but mixing paddles were a common component with a lot of these style of lanterns prior to the 80s. But they often wore out...
@Marco Carlo Ensure that you're using actual water clear kerosene (K-1) and not the tinted "heating" or tax free pump station kerosene. Another...
@Thillo Looks like a late run but genuine petromax. Check under the fount for the date stamp.
The wonderful thing about aluminum is that it's a very soft metal. Someone who normally works on classic car auto bodies and motorcycles can...
The valve is identical to the 285 and 295 and are infamous for the schrader valve acting up. Replace the entire valve assembly.
@WimVe I run the butterfly choked to ensure the mantle doesn't rip or overstretch when it inflates for the first time, then I adjust as necessary.
@WimVe The optimal position of the butterfly screw seems highly dependent on the mantle used and it's geometry after burning in. Sock like...
@Pdebruyn The 821 should have an air gap of 7-9mm as it's a 250CP lantern. You will risk back burn as too lean a mixture will overheat the inner...
@Tom Pedersen I usually fill right to the neck because that's as full it can get without it spilling out.
@Tom Pedersen That is really strange, the fuel level of the tank should in no way effect the burn of the lantern, either it has fuel and pressure...
You have a leaking jet, common problem with petromaxes. Tighten it up. Air gap on an 821 should be 7-9mm. As the lantern heats up, the loose...
Some formulations of Jet-A may contain a deicing agent mixed in that's pretty nasty when burned and may foul up your vaporizers in short order....
@Matti Kucer I use a metal bolt sized and tucked under the j-tube so it rests on it to achieve proper height. The screw on clamp now only has to...
@Thomas1 Pelam, one of the licensed company to assemble the lanterns sourced components from their sister manufacturer Santrax from Hongkong...
@Thomas1 Germany Regd on the fount does not mean actually made in Germany. Regd is means the lantern patent and design is registered in Germany....
@Parvis Notice how the section in the j-tube where the burner nozzle screws into has way more threads than you think it needs? That's there to...
@Piotrek I wasn't aware it was missing the top section of the hood, that part is pretty important to controlling the escape of heat and for...
If very concerned, you could maybe JB weld or solder a bracing ring on the bottom of your fount. @Piotrek
@Piotrek Pumping up petromaxes from experience, I'd recommend pumping until your thumb gets a bit sore which would pressurize your lantern right...
@Piotrek You indicated that you needed more pumping? One common mistake alot of petromax and clone owners make is misinterpreting the red line...
