Just got a Master built XL for father's day. I'm seasoning it today. so far so good. Read tons of threads before hand. loved them. Did a few recommended mods. 12" CI skillet on top of factory chip pan, ditched the factory water bowl. But I'm having a couple issues. 1. I'm using hickory chunks. but getting very little smoke. 2. with vent all the way open and gas all the way down, can't keep it below 245* any suggestions?
