The c-clamp would probably work fine, to press out the insert, as long as the carb/insert is placed between a couple pieces of wood, or something to protect the soft metals. I like your washer making idea. I really think that putting a washer on the inside, is the only way that the insert will stay in the right alignment, as vibration will likely cause things to shift.

Flyboy Dave's picture is a good duplicate of the carb I am working with, which leads me to believe that the specs are off at the factory. Has anyone made MECOA aware of this site, they should probably be made aware of all this information.
