are these thingys supposed to cotton inside thbottom part? well like i said i got this thing at a garage sale, i know it works b/c i did it once and it worked, but now i cant get it to light. i noticed that mine doesnt have a wick either like shown in all the pix. but it does have a butt-load of cotton in the fuel container. im really a rookie on these things and i dont know what im doing so if someone could help me out that would be great, thnx
