Hi fettlers. I encountered today an issue with my USSR record 1 stove that I run with gasoline ( not kerosene yes I know I shouldn't) At a moment the flame started to reduce until it disappeared but still hear the gas sound out from the jet. I though that the tank was empty so i opened the air release and the filler tank. But when I looked into the tank I saw that it was some gasoline. It was about 200 ml of gasoline when I emptied the thank. I refilled the tank with 0.5 liter of fresh gasoline and it worked very well. What could be the problem? Is the gasoline at the bottom that lost his burning capacity or the tube that don't go to the bottom? Do you have the same thing with kerosene? Regards.
Stove not picking up the fuel if the fuel level is too low maybe? Sounds like what happened. Type of fuel wouldn't matter in this case. Duane
It does sound as if the pick-up tube doesn't extend down far enough. Can you see the tube by looking in the fuel filler hole? it was perhaps soldered/fitted in the wrong orientation when it was made. Another option, less likely is that the tube has a hole/split which means it blows air out instead of fuel below a certain level. Interesting fault, let us know how you get on! Alec.
Thank you @Rangie and @hikerduane for you answers that what i suspected too. Maybe if I insert a piece of fabric like in regulated burners the problem will be fixed. I will let you know.
above could be checked at once - - dismount burner - fill the tank - a few stroke with pump - and the fuel should leak thru the riser -------------------- if in the tank was autofuel/benzin and after this heavier fuel preheated stove could work "like overpressurised" - no flame in combustion area just clean the tank - and try again
Hello and thank you for your replies I want to update this post with a test that I conducted on some stoves and I concluded that it is normal that some fuel will remain at the bottom of the tank and cannot reach the pick up tube. I pictured below every stove side to 0.5 liter of fresh gasoline side to what remained in the bottom of each tank. Primus no 25 USSR made record 1 Coleman 424 dual burner Shmel 1 Best regards
Hi @snwcmpr the kerosene is no more available in Morocco since too many years. The best substitute a found is the paint thinner with a flash point of 30 degrees vs -45 for gasoline.
Fuel present in a tank below the “reach”of the dip- pipe feeding the burner can be the result of an over pressurised tank which has distorted, permanently bulging the top of the tank upwards. This also lifts the fuel dip-pipe off the base of the tank. Other effects of over-pressurisation are distortion and possible detachement of the stove legs from the sides of their tank, plus buldging, and possible rupture of the tank. Kerophile.
@kerophile thank you for the link. never imagined that overpressure can deform the tank like a balloon. best regards.
