if you ask me, it seems like the linkage should reallly be replaced
tho you did unsieze it w/ wd40, it won't last long unless you use more lasting grease, but more so the fact that it seems it only moves when the motor is at the fastest and most powerful setting, hence the fact that it doesn't come to rest and just stops and only moves when at the fastest setting
