Here is my problem with the claim that a couple of people have made, that
these are "motor run" caps: They are clearly filled with paste, not oil (as
some has been forced out through the emergency vent hole), and they seem to
be marked with a "-" near one of the solder lugs. That strongly suggests to
me that these are electrolytic "motor start" capacitors.

Am I missing something?
