Hi there! So we just got a Weber Kettle and loving it so far. However, I am using hardwood charcoal and the starter chimney to get it going. I find that I have a very short burn time, maybe 30 good, hot minutes, and that the amount of charcoal is not nearly enough to cover the bottom of the grill kettle in a single layer. Any tips or tricks out there to light it up with the right amount of fuel from the get go? Do I need to get a second starter chimney?
