So i have tried to adjust the HST according to the manual. But it seems that is not the issue. the issue seems to be the little cylinder (damping lever) connected to the foot pedal. the one that is supposed to center the pedal. mine will not center the pedal completely. it always leaves it to whatever the last direction i used it in. I have checked and this part is expensive. is there a way to rebuild it or is there an alternative. part number 25 below.
