I have a Phenix stove -- after my wife's grandmother (teacher), who used it before WW 2nd, in '30s, to make a coffe, before housemaid started the fire in the big kitchen oven/stove. It seems to be Made in Poland, under Swedish licence -- the pressure release screw has pressed "Made in Sweden". The nozzle seems to be blocked, and one leg fell off. Also the pressure release screw is slightly leaking. I cleaned it (the fount was covered with black tar-like layer, probably non-pure petrol leaked and evaporated) with Turtle engine cleaner. It appeared to be more aggessive, than I've expected -- the fount turned yellow, to bare metal, not glossy. What can I do to the nozzle, apart of pushing a very fine wire in it? The rust remover (based on phosphoric acid) would be a more subtle method? Another thing it's brazing -- the leg was silver brazed, so I am in the process of buying Mapp-gas-like torch. The time of excitement is coming... The residues of petrol will be washed off from the fuel tank, I hope that the plastic hose connected to the tap should be OK and the dirt from the tank will go away (now I hear something loose in the fount). Any advice is welcome (apart of "Be afraid. Be very afraid" -- I already am... )
Most engine degreasers I have used contain caustic soda a strong Alkali you would be better to use a solvent ie paint thinners to clean crud. DO NOT use petrol in that stove it is designed for kerosene. A blowlamp pricker is what you need for the jet cleaning, there is a tool available for jet removal looks like a "T" with a swivel drive for jet if you cant hear air after empty pumping try removing burner and soak with carb cleaner.

This looks like an early Primus, though I do know that Optimus and Radius made rebadged product. It could have been made under licence in Poland, but suspect a lot was made in Sweden. Maybe it was only the final assembly that was done in Poland. The leg is only soft (lead) soldered on. A good plumbers solder is ideal. The size of the wire needed for the jet is 0.3mm. New jets are available, but it would be a good idea to remove the burner and give it a good clean. Heat and quench works well here.
Thanx! With soft soldering -- it would be much easier, and the pump unit will not get un-solder in the process.
I made a tool for cleaning of jet nozzle -- with wire from brake cable and piece of metal. Now, after pumping, the jet is hissing! The residues of kerosene in the fount were dirty brown... I suspect the kerosene/diesel fuel bought from Soviets in 1944/45... Some loose pieces of rusted steel (8x8, 6x8mm) fell off from the tank too. What method of cleaning of the fuel tank will be the best? Shall I pour in it rust remover (based on phosphoric acid), or orange peel grease cleaner? Or paint solvent would be better? I think that in the tank may still remain some pieces of rust, blobs of polymerised oil from un-cleared kerosene and stuff of unknown origin (Russkie's lard? )...
First, try cleaning it with some clean paraffin (kerosene) and a small hand full of ball bearings (or round fishing sinkers). See Jeff Johnson's post here: http://0flo.com/index.php?threads/4348 That usually is sufficient, unless there is a structural problem with the tank.
Cleaned the fuel jet nozzleI've had some break with refurbishing of the stove (other duties), but got idea, why the legs often snap off from the tank (which is quite popular). It's issue with overpressurizing of the tank. The legs, as stiff, do not keep bending together with the fount and the soldering breaks. The idea I have is to improve a little the stove ansd solder to the legs the brass plates, like on this Optimus, for to increase surface, where the soldering keeps: I am pretty sure that I have seeing similar solution in non-folding stove. Another thing -- you may excommunicate me for this...
I put in the tank a handful of M4 & M5 nuts + kerosene. What a mud was pouring from the tank! I left it for night to soak and will shake and pour off again.
