Well I finally got a chance to smoke some ribs since my last fiasco. I did CWM's (RIP) recipe except I used spare ribs again. I did fairly well keeping the egg around 210 once I got it there. After 3 hours or so when I tried to bump it up to 250 it took me a while to get it there and stabilized, I was on the low side so I think this had little effect on the outcome. After about 5 hours the temp jumped up around 290 to 300, I had trouble getting it back down. Bottom line is they ccame out a little dry in a few places but were much better than last time. I seem to spend a lot of time watching the temp guage and rest assured all my adjustments were very minute.
Next time I should ace it.
Thanks for everyone's help.
One item I noted was that when I opened the egg to spray the ribs every hour my temp would jump and not come back done without further adjustment....everything I read on the forum says it should come back and stabilize....I guess I have a cranky egg.
