I've noticed on our Buck 80, when all of the primary inlets are closed, most of the flame seems to be coming from the center of the stove. The 80 has individual controls for left, right and center inlets. Each is simply a rod connected to a flat plate that slides to cover or uncover the inlet opening.
During one of these low burns, I discovered that pushing down on the center control rod will pivot the plate upward (which will seal the the inlet more tightly) and reduce the amount of primary flame. Now when I want to have a really low burning fire, I hang a 1.5 lb. steel dumbbell weight on the center control rod.
IIRC, the 91 uses only two control rods - one for the primary left and right and one for the center. The control rod might be too long to use the same method I did, but if not, you might be able to tighten up the slot that the plate slides in with judicious use of a hammer.
