Hi! We picked up a Carona (dk17) kerosene heater at the thrift store. It looked to be in great shape except for the wick [sic] was burned right down to the wick Here's the problem: I can't seem to get the new replacement wick installed correctly so that it will adjust up/down, the material on it appears to be thicker than the old one. Is this common when replacing the wick on these stoves? (and yes, it's the correct wick that is meant for model of heater, so that's not the case). If so, how do I remedy this problem? Thanks in advance!
