  Clean engine (produced 1946-50) and a nice video.
Wanna swap for a B-30 or B-31?  The answer should
be no as yours is rarely up for sale.

  Regarding the S/V...I've added a photo taken from
the book 'Metal Ware Corporation' by Donald Stilson.
It is an exploded schematic view of an engine that
shows how the S/V is set up.  A skinny brass bolt
w/nut, a spring that fits and is a reasonable strength,
maybe a washer, and maybe some gasket material.  It
is kind of a 'Pull a rabbit out of your hat' sort
of job.

Good Luck,
Wayne
