Had my first cook in my UDS that was finished about a week ago... I had some temp problems and was hoping someone could enlighten me.

I lit 15 coals in my chimney. I've got 3 3/4" intake holes and 8 1/2" exhaust holes around the circumference of the lid. I put pipe nipples on two of the intakes when temps got to around 210. The third 3/4 is a ball valve and was left open. No exhaust holes were covered.

The temp climbed and ranged mostly between 280 to 300 it probably would of climbed higher if I didn't take off the lid occasionally to cool it off. I couldn't seem to bring it down with the intake adjustments. I also didn't want to completely close off my intake ball valve on the third hole. But, I did close it about half way. Still was hot.

There doesn't seem to be any leakage in the drum. When I close all the holes, the fire goes out pretty quickly. Any ideas on what I can do to keep those temps down? Do the exhaust holes need to be slightly bigger?
