I finished my UDS today minus the green paint which will be next week, named it Frankenstein. I have both a Weber style lid (Not Weber) and the drum lid with 2 bungholes. I'm having trouble getting below 300 degrees with the Weber style lid and 275 with the drum lid. I had all plugs on and the valve nearly closed and was steady at 300. Here are some pictures, notice how closed my intake is. Any advise?
