SBS did the motor turn real slow and stop.. then when you start it turning again it slows down again and stops?
That's sort of the way it acted before I spritzed it with WD40.
And, WD40 is a light lubricating oil in a solvent. The oil lubricates AND acts as a moisture barrier/dispersant, while the solvent helps to disperse the solution. One reason WD40 tends to work so well on previously lubed parts is that it helps clean the gunk and such away (via its solvent fraction) and leave a nice thin layer of lubricating oil.
