Got home from work and decided to play around with the smoker for a bit. First thing I learned was split size is crucial, 7-9 inches work great, hold temp under 250, burns for about an hour. Second thing I learned it fire placement plays a big role in keeping wood burning. Third thing, using just the firebox door to control the flow of air let’s me get my temps within just a few degrees from stack to firebox. Thank you for all the advice, will be doing more smoking this weekend.
I have since sold my Pecos , but here is what I used to do.
1. I put bbq adhesive gasket on the smoker around the lid , helped tremendously with heat and smoke loss
2. I pulled the metal grate from the firebox and made my fire without it, putting 2 logs along each side and then more rows cross hatch like Lincoln logs really high and let it burn down to a large bed of coals to start the fire and then would feed the fire with 8-10” splits about 3-4” in diameter. Using the door itself is the easiest way to control airflow with the stack pipe wide open always to keep the draw consistent
3. I drilled holes in the lid for a thermometer 2” higher than the cooking grate on each side to see what left and right grate temps are at all times so I know how to adjust the fire
4. I would use a small metal fireplace shovel to push and pull the fire closer or further from the cooling chamber opening in the firebox to control the heat if the right side is too hot, move the whole bed of coals away from the cooking chamber side and vice versus
5. Use steel plates or buy something to use as a he’s deflector for where the smoke enters the chamber , it gets real hot for me Until about 10–12” away from the opening from smoke box to cooking chamber
6. If it’s colder than 40 degrees use an insulated blanket over the cooking chamber
7. Place all of your splits on top of the firebox lid to heat them up prior to putting them in the fire, they will catch right away if you do this and keep you from having to mess around with the fire going out as when you add a log
If I think of anything else I’ll chime in but the thread has a lot of good stuff in older comments with pictures
