gasoline blowtorch
I just picked up a Turner T15C gasoline blowtorh, "new" and unused with
instruction manual but a little shelf worn last week. From the appearance, it's probably 30 or more years old. The leather gasket in the pump is good, the check valve is good, the wick looks fine and the orifice isn't clogged, but something like rust or black powder came out and there appears to be no seal along the valve shaft and the packing nut on the read. One website suggests this can be replaced with grahpited string, like on a steam radiator valve. I went ahead and fired the thing up with camping gas and it did light but made a weird pulsating sound, a little faster than once a second and the flame never really looked right with a yellow tip. I also noticed that in the off position, the needle from the needle valve actually stuck out from the orifice itself by about 1/16th of an inch. I suspect this isn't right. Any tips for dealing with and fixing these things? The stuff on this site really doesn't really dig too deep http://www.blotorches.com/torchfix/t...ml#operational Any good stories of using these or advanges to propane torches? |

I dunno about the other stuff but the needle valve is probably supposed to stick out so that it cleans the orifice. Oh, and the pulsating may be because it is not getting hot enough or because the fuel flow out of the orifice is not consistent. This may be caused by a clogged filter or by the fuel passage under the burner assembly being partly plugged with carbon deposits. Eric |

Most of them DO pulse a small bit, just a heads up. But if its really noticable...you are probably sucking air and need the seal for the valve. And they are far cheaper to run than propane torches if you need to use it on a Sunday and your bottles are empty. They will also run on Kerosene and diesel (smokey and dirty and nasty..but working) and they will run nicely on Coleman fuel (expensive) I see you were using it with "camping gas" which I assume is Coleman fuel. Try it with unleaded gasoline, but replace that seal. as for the needle sticking out..that is probably normal. And you did light a heating fire in the preheat trough underneith and let the torch head heat up properly before turning on the torch itself..right?

: I also noticed that in the off position, the needle from the needle valve actually stuck out from the orifice itself by about 1/16th of an inch. I suspect this isn't right. I suspect it is. Pushing the needle through the oriface varies the ORIFACE area, instead of just the liquid flow TO a fixed oriface. That makes it work properly at a range of pressures, instead of just at one.

BTW... did you fill the generator cup, and get the generator _good_and_hot_ before trying to light the thing? It's NOT liquid-fueled at the burner. It's gas(seous) fueled at the burner, just like a Colman lantern. If you didn't get the generator hot first, it's going to do all sorts of choking and pulsing, and even shooting out burning liquid. What you describe sounds like there's still liquid fuel reaching the burner. Lloyd |

It was no real surprise there was gas all over the place when I was done. |

As to that...I never take a propane cylinder off once I install it. Well..Ill take that back..I do have several of the cheapy propane torch heads that come in the little box with some accessories and a bottle..and Ive bobbed the torches down to the valve, plugged it with a proper plug and screw that onto the bottle if Im removing it from another device. That way I know the ******* isnt going to leak out before I use it again. I was fortunate enough to score a full Case of propane bottles at an auction and found about 8 of them were MAPP gas, the other 16 were propane. Not a bad deal for $3 plus 16% buyers premium...eh wot?

The stuff on this site really doesn't really dig too deep http://www.blotorches.com/torchfix/t...ml#operational Any good stories of using these or advanges to propane torches? Let's put it this way - there is more than one reason they virtually dissapeared when BernzoMatic introduced the propane torch in the 'fifties. Otto Bernz's new propane torch made his old "always reliable" gasoline torch obsolete virtually overnight. The gasoline (and in europe, Kerosene) blowtorches have a fussy "generator" that needs to be pre-heated to vapourize the fuel before it works right. There is a "puddle tray" under the generator/nozzle that you need to fill with fuel by dribbling it out the nozzle. You then light the "puddle" and let it smoke for a while to warm the generator - then you open the needle valve to see if you are still getting liquid or vapour. If still liquid, shut the valve and let it continue to heat. When you get vapour it will light and burn smoothly. If there is any liquid you get the "putt-putt", the yellow flame, and low heat. If the generator carbons up it has to be dissassembled and cleaned.(or more likely replaced - they are fragile and fussy from what I remember) It has, if I remember correctly, a spring like heat exchanger in it that can be easily damaged. (just like in the old coleman stoves) If it is a brass one, polish it up and show it off on a shelf in your shop. I used to have a couple real nice ones - but only used them a few times, along with a big "tinner's copper" for soldering eaves troughs, and for thawing pipes on the farm. |

What you describe sounds like there's still liquid fuel reaching the burner. I did take a peek at the air inlet and there wasn't an stream of liquid gas once it was up and sort of burning. I'll check on the filter screen, repack the valve stem area and give it another shot this week. There's anecdotes on the internet that propane is hotter, and that gasoline torches are hotter. Kind of eager to find out what the deal really is. For whatever reason, I tend to end up with more and more propane cylinders that don't reseal when taken off a torch. Pretty obnoxious. As to that...I never take a propane cylinder off once I install it. Well..Ill take that back..I do have several of the cheapy propane torch heads that come in the little box with some accessories and a bottle..and Ive bobbed the torches down to the valve, plugged it with a proper plug and screw that onto the bottle if Im removing it from another device. That way I know the ******* isnt going to leak out before I use it again. I was fortunate enough to score a full Case of propane bottles at an auction and found about 8 of them were MAPP gas, the other 16 were propane. Not a bad deal for $3 plus 16% buyers premium...eh wot? good score. I'm down to one can of real MAPP. I see there's stuff in yellow cans, but it's not the real deal. Not sure how it behaves compared to the real stuff. I used to use real CFCs in a can for spot cooling electronics, none of the safer for the ozone stuff behaved anything like the real stuff. |

I virtually ALWAYS leave them on the torch, for that reason. The coleman stuff is AWFULL - the genuine bernzoMatic tanks have not (generally) caused a problem for me. I have an "adapter hose" for running coleman stove off 20 lb cyl that I have my torch head attached to - shouldn't run out of propane for the torch for another 10 years or so!!! |

Most of them DO pulse a small bit, just a heads up. But if its really noticable...you are probably sucking air and need the seal for the valve. good call. I re-dissambled it and the "rust" that came out does appear to be a completely deteroriated seal, so yeah, air might be sucked in somehow along the valve stem. that could probably be fixed with a stack of proper sized O rings. And they are far cheaper to run than propane torches if you need to use it on a Sunday and your bottles are empty. They will also run on Kerosene and diesel (smokey and dirty and nasty..but working) and they will run nicely on Coleman fuel (expensive) I see you were using it with "camping gas" which I assume is Coleman fuel. Try it with unleaded gasoline, but replace that seal. I just got a can of "Crown camp fuel" "for gasoline lanterns and stoves". The original manual says "any clean gasoline" or "white gasoline". The crown stuff has a rust inhibitor so I got that, the colemen stuff on the same shelf at REI didn't. Nobody really knew the exact differences between the crown, coleman and MSR branded fuels. The stuff seems to smell more like naptha than plain gas. it IS naptha. All of it. White gas, Coleman, WallyWorld trail fuel, camp fuel etc.. naptha Fortunately...these torches will burn just about anything. Diesel..you really have to heat up the head so its almost not worth it..unless you only have diesel and no other fuels. And I shouldnt have put in "unleaded"..as the torch simply doesnt care what goes into it, leaded or unleaded. Leaded fuel ruins the generator on them pretty quickly - but then other than AveGas or racing fuel, that's not an issue today. as for the needle sticking out..that is probably normal. This is good to know then. I need to figure out how the shut off really works, or what the seal in there is or was. And you did light a heating fire in the preheat trough underneith and let the torch head heat up properly before turning on the torch itself..right? I did fill the cup and light that to heat up the burner. Prior to that I did a leak test and the fuel valve does leak a bit but when opened makes a nice stright jet of gasoline. Once warmed up, no more stream of gas came out, but what I assumed to be vapor. Not a bad video about care, feeding and lighting https://www.youtube.com/watch?v=346meunDloU I saw this one- but I was working outside. It was no real surprise there was gas all over the place when I was done.

I dunno about the other stuff but the needle valve is probably supposed to stick out so that it cleans the orifice. Oh, and the pulsating may be because it is not getting hot enough or because the fuel flow out of the orifice is not consistent. This may be caused by a clogged filter or by the fuel passage under the burner assembly being partly plugged with carbon deposits. Eric Unlikely, being a "new in the box, old stock" item. Yep, unlikely. I would check anyway if nothing else worked but N.O.S. would tend to make carbon clogging unlikely. I read his message twice and still put that bit in about carbon. My only hope now is that he tries everything else and then finds a bunch of carbon clogging things up and vindicates my advice. Thanks for pointing out my goof. Eric |
