[oletrucks] dual carb tool

["Alan Lubow" <alosteo@uswest.net>]

Grant:

I think you're talking about a Unisyn.  It's a simple vacuum gauge you set
on top of the carb.  A little ball in a glass tube rises to different levels
depending on the vacuum.  Then you pick up the tool and and set it on the
other carb to compare, adjust second carb to the same ball height and you're
done.
