Why won't my lantern relight after it has been rebuilt?

Haven’t delt with one of these in forever. But I’d clean as much as I could with floss and a pipe cleaner. And sometimes just to relight I’d put pennies over each hole until I got it to light. Once it was going I didn’t have to worry about the holes. Also the gas can create turbulence in and around the mantles at even the lowest output, Keeping things from lighting. Hope this helps.
