New to kettle grilling. Not sure what my issue is - I put the burgers on the hot side until they got a nice sear, but then put them there hoping they would get to temperature (160) but it took forever and they weren’t getting much hotter - I had to close the lid and even then it took so long and they were stuck at 150-155 for a few minutes. I admit I was checking temp more often than I should, but shouldn’t the coals be super hot? Am I using enough coals, or the wrong type of coals? The last time I made chicken legs, the same thing happened and I could not get them to temperature high enough (they were stuck at 160 in indirect heat).

Any help is appreciated!
