    Removed the carb today to have it rebuilt and noticed a spacer under the carb. The spacer is approximately 1" thick with a gasket on the top and bottom. Is the spacer factory or is this something thrown in by the previous owner?

    Is it a plastic-like material?

    Phenolic spacers are used to insulate carburetors from the heat of the intake manifold.

    Not so much for while the engine is running, but when you shut down a hot engine, the heat from the intake manifold can boil the gasoline in the carburetor fuel bowl. This makes it very difficult to restart a hot engine.
