Got my new cooker home yesterday & on the deck.
Fired it up this afternoon , no cook just charcoal.
Temp peaked around 450F with ALL vents closed
Back to drawing board, fixed two air leaks , one with flexible fridge magnets & 2nd with a washer & bending a door.
Second fire better, temp peaked at 325F but no cigar
Used Permatex high temp gasket material to cut down on leak from section 2 to 3, it's curing , next try tomorrow!
Kinda sad I've got all this stuff around the house & it's all been used on cookers before
