Old MSR Firefly I resurrected shown with a BerniDawg Midi-cap. "Curious about your reservation regarding methyl hydrate?" None, just a mention of toxicity for those who refuse to do proper diligence. Ethanol is often mixed with other stuff hence the smoke. Methyl hydrate, methanol, methyl alcohol, all names for the same thing and vary with countries usage, similar to the English terms for white gasoline, naphtha. butthead |

Anyway, it now runs smoothly proving the chugging was caused by the bad o-ring and not old Coleman fuel (container opened two years ago). |

The problem I have is that I cannot obtain the service kit for this stove locally and maybe not in time for my trip in two weeks. If this was you, would you just get an aftermarket gasket with the same dimensions? |

Primus does sell maintanence kits $25, but my favorite source for stove parts is Needle Sports who carries a large selection of Primus and MSR parts. butthead |

butthead: "Old gas is seldom the cause. Crown and Coleman fuels are filtered and refined to provide a stable long storage fuel. An air leak is far more likely. Chugging can also simply be a mismatch in the supply pressure. Thanks butthead. The broader issue is the relative scarcity of specialty products available in Canada for a variety of reasons - distribution agreements, legal restrictions, and more generally a difference in national consumer cultures. So when it comes to a variety of products discussed on this chat group that I've come to possess, I've had to beat the bushes hard or shop State-side which is significantly more expensive. Permithrine - can't get it here Dynema - hard to find Hammock choice and attendant accessories - limited and hard to find. Denatured alcohol in limited sizes - forget it. Primus maintenance kit - finally found one available from an online distributor I thought was in Canada but may be American (trying to distinguish between Canadian and American commercial web pages is a PITA in Canada. Sometimes the price looks too good to be true, then you realize it's a US operation in $US. That's a whole different issue). MEC carries my stove but doesn't carry the maintenance kit. That's a sample. Oh, but if you want marijuana or codeine...that we have. But having said all of that you live in the land of plenty but your link references a UK website. That's interesting. |

I not only collect but experiment with mine. I will suggest alternative descriptions for alcohol, Heat gas line antifreeze is a very good fuel and available in ethyl alcohol and methyl varieties. Marine stove fuels often methyl alcohol so maybe a marina could supply you. butthead |

Bring your old o-ring with you and ask for a Viton o-ring of the same size diameter, and same size of the o-ring itself. Viton is what you want because it works better in fuels and oils. If you can’t find Viton o=rings, Regular o-rings made of rubber will get you through a trip, but then you will want the correct material. For installation put a dab of silicone synthetic grease on the o-ring spindle and the o-ring. |

butthead: "As a collector of MSR stoves I searched long for a source. In the USA MSR supports only factory repairs/rebuilds. Want to use XKG jets in a Dragonfly? You need to do it on your own and if such a stove goes to MSR all non stock parts will be replaced. Heet in the yellow bottle...yes that came up in my research as the leading contender. Only available at Amazon.ca for about $20 and may not be shipped in time for my trip. Curious about your reservation regarding methyl hydrate? Several reports online suggest it although there are warnings about toxic fumes. But we'll always be using it in the outdoors so I'm not concerned about that. I tried it already and it worked perfectly - very clean burning too. Our Swedish alcohol stove lists the various suitable products by country for cooking. Methyl hydrate is on the list for Canada but not denatured alcohol (which is on the USA list). Ethanol products are favoured over Methanol for heat but produce more soot. As soot is what we are trying to avoid in the priming process, methanol derivatives would be better no? Appreciate your input. Thx. P.S. Out of curiosity, how many MSR stoves do you own? |
