Hi Ken; It's not a matter of re-jetting as I said the fuel has to be boiling in the generator tube so that it is vapour which reaches the jet not liquid. As long as there is enough heat it works great. Given enough time a sterno flame can no doubt heat things enough but the problem is generally the preheat fuel (sterno or whatever) burns itself out before everything is hot enough. You could probably just re-prime it maybe twice or three times before trying to light?? Joe Ken Dunn wrote: Well that's bummer-style news there, Joe. I was hoping to use a multi-fuel stove on the trail as well as for preheating my biodiesel process. Of course, I suppose it would still be an improvement to use the stove for preheating wvo to make biodiesel even with the propane used from the torch to preheat the stove. Better than electricity or another petro based liquid fuel through out the whole process. Have you made any attempts to change the jet size on the stove? Would that be a worthwhile endeavor? How about adding acetone? (just kidding).On 12/6/06, Joe Street <[EMAIL PROTECTED]> wrote:I use jellied alcohol (like sterno but runny) for pre heating my stove on the trail. It wasn't enough heat for the biodiesel though. Even with kerosene it takes a prolonged period of preheat with sterno to light the stove. If you turn the fuel valve on prematurely you get liquid coming out the jet rather than vapor and then the liquid just burns with an awful sooty yellow flame. With naptha (white gas) starting is a snap. With kerosene it takes careful preparation, a wind screen and enough sterno. With BD it takes a torch!

Is kerosene the most logical agent to cut the BD with? Joe Street wrote: Hi Mike For what it's worth I tried running my multifuel backpacking stove on BD. I had to warm the preheater / vaporizer tube with a propane torch to get it hot enough to vaporize the BD. Once lit though it had a beautiful and stable blue flame and judging by boil time comparisons roughly the same heat as kerosene. Esters have a high flash point and need a lot of heat to use in a stove that is designed to supply vapor to the jet. Joe Mike Weaver wrote: So far all attempts to light it have failed. It's 30 degrees here and that may have something to do with it. I cut the BD w/ a good shot of Dino diesel and still no go. I got the preheater going but no flame on the ring. I brought it inside overnight to warm up and will try it again. If it doesn't go I'll mix in some kerosene. The booklet says you have to preheat for 3 1/2 mins sometimes to get BD lit. It came smelling of kerosene to I expect the factory lit it and tested it. FWIW the pressure gauge is bad but it does hold pressure. I had hoped to use it to heat oil so the the bd process was all fueled by BD. I also looked at some of the camping stoves but they are very expensive and designed to be as light weight as possible. The guy at the camping store said the thinner distillates works best. We'll see, Mike Ken Dunn wrote: Please, let us know how it does, Mike.

Will report back if I get it going. Ken Dunn wrote: What is everyone using as a heat source for preheating? I'm thinking about buying the BriteLyt mentioned on JtF. I could use it for other purposes as well which would be nice. Anyone test it? Care to comment?
