greetings everyone and welcome to Lantern lab today we're going to talk about how to light your white gas Colman up line here we've got a Coleman 335 this is a Canadian model a lot of you Americans may not have seen the first thing we'll do in any case where we're gonna light a lantern is just to take a look at it we want to make sure there's no stress cracks we don't want to see any leaks coming out of the bottom let's see that the mantle is intact doesn't have any cracks or holes or splits everything looks good yeah make sure that the fuel caps on tight we're gonna pressurize the lantern I just put in ten strokes and we want to let go of the the pump and just put your thumb over it and see if there's pressure not that I can't push in but there's no pressure pushing out pressure at this point forcing the pump back out would tell us the check valve it failed a failed check valve is not a safe situation I'm gonna put it in I'm gonna put it in about 25 palms that's good to get us lit but it's not gonna be enough to run the lantern not at full brightness anyway but then we'll get us started now I'm gonna crack the valve and I'm gonna listen and the lantern will spit so what's gonna happen normally is you'll get this just flow of air and then it's gonna make a different noise when it makes a different noise and turn off the valve this 335 in particular tends to take a long time before it starts this bit if yours never spits we probably have a problem with the fuel air tube inside the tank well let's give it a shot got it match lit drawn good under the mental crack the valve where we go sometimes need to flip the cleaning rod we're doing this now once you're burnin sometimes you get a little too much if you can't flame up here turn the knob off and wait a second once your burning good crank them out open pretty much as far as it'll go may also need a clue flips of the cleaning knob when you crank the valve open you may hear a click or a pop that's the the fuel air tube there's a rod in the fuel air tube and it's the rod moving in the fuel air tube so we're burning good we got no big flames yes bunch more pressure you can hear that the lantern makes a lot more noise easily pump until I feel a significant pressure against the pump some lanterns will pulse if there's too much pressure someone lanterns will pulse if there's not enough pressure some lanterns want to be lit with very little pressure my 3:35 here isn't real discerning I did 25 pumps today I could do a lot more the AGM lanterns don't have a real fuel air tube like the coments do so they want generally want a lot more pressure the milspec lanterns want very very little so it's all about the lantern that you actually have and you're gonna have to experiment some to find out what the the magical combination is for your lantern that seems to work out fine I'm gonna close the valve all the way and it's gonna take a while for the lantern to go out and this makes some people very uncomfortable but you know if your tent camping you can consider this feature you can check the lantern off and there's plenty of time to scramble back into your tent with the exception of some of the very early Coleman lanterns though the two mantle white gas lanterns light pretty much the same way the singles do we put in the pressure crack open the valve listen for the noise then apply the match and off you go so I have already put the requisite 25 pumps into my 220 F here let's crack the valve and see what happens it's just about to give up on that one because we don't wait so long I'm gonna put in maybe 10 more pumps on a very new lantern or a lantern which has never been lit before you might have to wait longer you might have to pump up two or three times but usually 10 or 15 seconds is all it'll take match get a little pulsing a couple little bursts of flame that's no big deal at all wait for it and that changed right it got burning better now we crank the valve still getting a little extra flame so I'm not going to apply extra pressure yet dose the cleaning valve there we go it's cold out here so it takes a long time sometimes there we go we're going good now you have both white gas and kerosene lanterns it's worth thinking about exactly what kind of lantern you're working with in any given moment so that you don't shut it down in a way that's dangerous this is a 220 F that's a white gas lantern so we will definitely not be opening the fuel cap valve only this is Kurt for Lantern lab thanks for watching
