And the aperture/shutter blades had grease on them after I cleaned the helical, so I spent about another hour with the lighter fluid and Q-tip cleaning the blades and running through all the shutter speeds. It seems to work at all shutter speeds now, but the slow ones sound slow. I plan to send it off for a CLA before too long.
