replaced the firepot in my fec 100 last year and ever since have had problems with one side of brisket getting burned. i set the temp at 234 for all the cooks typically i wrap my briskets in the 160-165 range. prior to changing the pot there were no issues of burning briskets. i use the same pellets from cookshack. any thoughts? does anyone else have this issue after replacing their firepot?
