I have a brand new IM Corona Old Boy which sparks but won’t light. The lighter worked for about a week and now it won’t light at all. I’ve tried bleeding and refilling a number of times and no dice. I’ve also tried bleeding with the cap open and refilling with cap open at the beginning and then closing the cap. I’m using Xikar fuel and starting with the flame on the lowest setting. Any suggestions would be much appreciated, thanks!
