I am working on a 1940 Neptune 1.5 hp. The carburetor and powerhead were painted a bright silver color. I do have a spare carburetor that is also painted silver along with a couple more carburetors that are not painted. Were they originally painted silver or was this done by someone to make it look better? When I was restoring my 1953 Evinrude Fastwin, that carburetor was painted the same color as the motor. That carburetor did not look like it was ever removed from the motor and the paint looked original.
