Hi all. Was hoping that someone might be able to help me. I have a UDS I built, using slide type intake, 2 inch exhaust, approximately 12 inch diameter by same height basket, approximately 4 inch tall legs. My problem is that I can run 375 plus all day. But I have to keep an insanely small gap on my intake, less than a quarter inch with 2/3 of the vent taped off. There is no other air leaks, I can shut it down and kill it with no problem. If I try to get below 250ish, it just doesn't want to run at all. How do all of you get the lower temps?
