Having constant issues with my UDS! I can not hold constant temp no matter what i do! Everytime I cook this happens, so that tells me either I'm consistently screwing up or something is flawed on my cooker.
This morning at 4:30 started a Pork Butt got my temp up to 250'F before putting it on, and have been fighting to hold between 225-250'F all morning so far, either drops down to 200 then I open valve more, skyrockets up to 280 while waiting for it to equalize, back off then drops way down again. I'm waiting anywhere between 20-30 minutes before making adjustments. I've tried micro adjustments on ball valve. Using 2 ball valves, 1 completely open by itself and temp goes down, open second maybe a 1/8 inch and temp jumps into 270-290 range. What the H-E-L-L?
