Sounds like its blocked, have you tried turning upside down and giving it a good shake? Whisperlights have a clever self cleaning mechanism than involves shaking. Otherwise give it a poke with the cleaning tool it should come with.
Whisperlights, when they work, should burn any old shite. Allthough mine only now runs on Coleman fuel. Probably because I spent years burning any old shite.
