Title: Yellow (gold) plated carburetor parts.
Post by: 66candy on May 28, 2010, 08:14:59 AM

Lately I see beautiful "concours" restored 2100 and 4100 Autolites with lots of yellow or gold plated parts. Almost every part which is not made of alumium is plated in that color: choke and throttle plates, linkages and even the air cleaner stud. Is this concours correct or just for the looks?

Here's an example:

It is mostly correct.

Can you elaborate, Charles? As far as I know, the Idle speed screw/spring and the carb stud should not be in that finish.

Idle screw and spring are typically zinc dichromate.

Otherwise, couple minor observations:

-Primary throttle shaft return spring is typically light blue color, almost like silver blue.
-Accelerator pump cover and secondary pump cover should be more of a natural color (not the holley style)
-Hard to tell in the pics, but the butterfly shaft should be brass
