Could use some help guys struggling with my first cook got the Kohl’s going good and hot. I made the mistake of letting it get up to 500 and I can’t get it back down into range. The only way I can get it below 250 is to slide the charcoal out of the way With both dampers closed as soon as I put the charcoal back in it’s skyrocket to 350. Do I have too much fuel thanks for any help
