[Spridgets] Carb sysn

[Seth Jones]

Not sure how this unit worked, but it appears in a factory SU carb manual
somewhere.  It looks like its a special vacuum gage that can compare two
vacuums somehow.  a mechanical device such as this would be a much better
solution I think because it wouldn't require batteries.

BTW Uni-syn syncronizers have been around longer than you might think.  Here's
an ad for them from 1962 as it appeared in car and driver
