How can only half the pot be burning and not fill half the ash tub with unburned coal?
If the worm and bushings are new, I would look for warped burn plates and/or air leaks. Make sure the air chamber doesn't have a buildup of fines, and also check to see if the pot is close to level.
What are you using for a coal size, feed rate, and air setting?
