Hello,
my name is Timon and I live in Germany. As a hobby I rebuild and restore carburetors, mainly Autolites 2100/4100.
Today I have received a C6ZF-F from a friend and I want to get it as close as possible to a factory look.
What I have the most problems with is with finding the correct finishes for the parts, especially the steel parts and I wondered if anyone here has pictures of a NOS C6ZF-F or info on the finishes used.
Here is a list I have started:
Screws:
Airhorn, Powervalve, Choke, Secondary Cover, Accelerator-Pump, Idle-RPM, nut on primary shaft: zinc blue
Booster to main body (primary and secondary): Zinc but not sure if blue or yellow
Choke plate to shaft: Black (black oxide?)
Idle mixture: Zinc (blue?)
Linkage parts:
Accelerator pump rod, secondary rod, choke rod: zinc but not sure if passivated?
Choke brackets: Zinc yellow
Choke plate: Zinc (blue or yellow?)
Throttle blades: Zinc blue
Primary throttle shaft: brass with a durable silver coating (chrome?), the steel parts on the end zinc with uknown finish, the spring zinc blue
Secondary throttle shaft: bare brass, the steel part zinc with unknown finish
Accelerator pump arm and secondary arm: zinc yellow
Zinc diecast parts: Boosters, acceleratorpump cover, powervalve cover, seoncary cover: yellow chromate finish
Paint markings:
Secondary booster: 1 red paint mark on the "arm"?
Primary booster: no idea
Any more paint markings?
Here are some pictures of the carburetor. As you can see it has been rebuild some time ago and it is quite difficult to identify the original finishes and there are no paint markings left.
Thank you!
Timon
