Yes what others above have been suggesting....Since I'm a visual guy, I thought I would add a few pics of what the fire should look like as well as the smoke coming out the smoke stack. Notice how clean the fire is burning. Additionally, notice the solid coal base and plenty of space for proper clean combustion. These are from a reverse flow as well as from a hybrid vertical.
fire for brisket - 225 - 235 range
End of brisket cook fire 225 range....notice clean burning fire and coals both wood coals and engaged charcoals
Beef rib fire 275 - 295 range....
.
Tomahawk steak smoke 220 to 225 range
Notice the very healthy coal bed with only one or two splits at a time and they are fully engage.
TBS out the stack, in the sun it looks like zero smoke, but there is thin blue smoke that has a sweet smoky smell and not a bitter burn to the nose and eyes like the thick white smoke.
Example of the color on the baby backs after 4.5 hours of this type of fire and smoke at 225-235 range.....they have an IT of 203
Hybrid vertical - larger fire is needed for the smoker volume but notice the fully engaged logs and clean burning. Not as clean as the reverse flow but still yields a nice thin blue smoke....
This is after 4.5 hours and I'm starting to glaze them with sauce......These have an IT of 198 but they have 20 mins more so will be 200ish IT
Notice the overall level of smoke in the vertical....it is very clean and again not "burny" on the eyes but a sweet smoke.
Start with a chimney of fully engaged coals then put 2 - 2" to 3" size splits on the coals to to fully light. Let them burn in and your smoker should be at a nice temp(should take 30 to 40 mins to get is ready)...Then add a split as the temp drops to 220 degs or so and as the other splits have "burned out" to coals....It will probably be about 25 to 40 mins or so between adds.
