Hello. This is my first post on the forum I ordered a roger's stove off of ebay advertised as "Project" because it "could not build pressure when dry tested" I think i paid too much, but i had been eyeing these and it came with the case and all and i just had to have it. This is my first 'backpacking' or liquid stove ever aswell. I got interested in it because i bought a lot of 6 coleman lanterns from a gentleman off Craigslist in order to resell. After making a big profit and keeping one of the old vintage "unleaded" ones i was shocked to know this stuff even exists. Growing up we only had the dual burner propane or propane fueled mantle lanterns, not white gas or let alone auto gas fueled. Anyways lets get on with the repair photos i fiddled or fettled with. This is how it came to me inside the canister. The two knurled rings where insanely siexed together even after lots of kroil. I had to use a vice and a couple of rags with some big ol plyers to crack it loose. Inside the spare parts tube revealed a 'vaporizer' NRV pip cup spring and seal, and a pump leather, as well as two graphite packings that split into 4 total pieces. For some reason there was two black gaskets under the pump tube... im not sure why. The old punp leather was screwed up. Trying to remove the flathead that held it in was a huge challenge. I heated the hell out of it and it stuck in hard. I had to use the vice AGAIN in combination with my hands to crack it off because i just didnt have the grip on that narrow pipe. Oiled up the spare leather in some used motor oil. After reassembly i come to find the pump handle is rising and making some interesting noises and wont stay down. Everything tells me its the ancient hard rubber pip seal & the spare one was even more solid. Full disclosure: i already bought a rebuild kit and repro wrench from Old coleman parts as due dilligence. But my impatient @$$ just wanted to see this thing fire off; so i went to harbor freight and bought viton o rings and hole punches. I ended up using a 3/16 holepunch on a section of fuel hose i bought for my motorcycle. Stuffed it into the spare nrv cup n spring, slammed it home and it worked! i think. I swear i hear the faintest hiss out of the tube like a mouse pissin on cotton but i cant tell. Seemed to pump up strong. So i poured gas right out of my motorcycle tank and fired it up and voila. The gas coming out on 'LIGHT' was really sputtery and not really a stream. I had to let it fill the pan for longer than 3 seconds. the asbestos wick is present and even in a fair bit of wind here it stayed lit and i was able to just turn the gas on and it ripped. Took a while to get a reasonably blue flame. Anyway, im glad to get it and i can see myself collecting perhaps a older coleman single burner!! this thing is badass. Thanks
Welcome, good job getting it going. Always nice to find surprises inside pump. Easy to check pump for leakage with soap bubbles or quick dunk. Can leak at valve packing, 1/2 turn might not hurt. Water will not hurt it and don't want leakage. Maybe time to get a gallon of white gas? Light the M-1950 up on Monday for the fallen.
After investigating the cause and making appropriate repairs, I can't express the joy I felt when the tool returned to life. I think everyone here will understand. Congratulations, it looks like you repaired your stove properly!
I just have it half full of ethanol free gas out of my kawasaki. I will have to invest in some coleman fuel seeing as now i have two appliances that run off it. Im interested to know how you remove the 'vaporizer' and all without taking the wind screen off? the spare one looks dirty so im assuming the one inside been ran hard for a long time with gas too. Thanks for the warm welcome
Here is an update. I gave it a degrease and pressure wash. The old asbestos wick got soaked and just looked tired... so i pulled it out of the priming cup. Cleaned the generator in it, the spares actually look brand new with fresh clean brass mesh. Put in a m1950 pump rebuild kit from oldcoleman parts and it made a world of difference. I got a clean blue flame only 60s of preheating... I am debating weither or not to fully sandblast the tank and the shield, repaint and put new decals. There is a absolutely ginormous dent in the tankside, so i figure i might aswell just run this one hars and put it up wet like it was meant to.
i wouldnt sandblast the tank. It will thin the metal. Ok not much but would you gamble with a pressurized tank full of highly inflammable liquid an inch from a big flame?
