Al,
I'm having a bit of frustration with the UDS.
On our first test burn 2 weeks ago it held for hours, we were really looking forward to using it properly.
However when we did our first cook on Saturday it would just not hold temp. We had all our vents uncapped and the ball valve fully open, but the charcoal only took near the ball valve.
The bag of lump we had was crap, mostly small bits, so I'm thinking it was that for now, but I'd be interested to hear if you had any alternative theories.
