I have an Oklahoma Joes Longhorn combo and have been messing around with the smoker. I have done ribs and a pork butt so far and they turned out good, but I get major temp fluctuations from 275-225. I start by doing a full chimney of lump charcoal and get it burning properly then put it in the firebox and let it go for a bit. Once it settles the temp is around 300* then put in 3 warmed wood chunks and let them get going. The temp gets to about 275 then I put the meat on. Then about 30 mins later the coals seem to be about gone and the temp is rapidly declining to about 225. I then add more chunks and it gets back to 275 then about 30 mins later it gets back down to 225 and I don’t know where to go from there as the coals are gone and the wood is about out. I am new to smoking and would love some input on how steady your temperature should be and some tips.
