In addition to the increased load generated between the spindle tusk and the droop stop through bolt the forces exerted on the through bolt when the blade is pulled down are transferred to the teeter bolt increasing the friction load. This further exacerbates the problem. If you want to lower one blade you must raise the opposite blade.
It is the combined friction of the spindle tusk on the through bolt and the friction applied to the teeter bolt that maintains the blades in the static condition.
