Title: Need help decoding an Autolite 4100 carb tag and carb.
Post by: cleandan on February 10, 2025, 08:20:58 PM

I'm trying to figure out what application this Autolite carb was used.
I've had this carb on my shelf for a long time, fully rebuilt and just waiting for a need.
The carb is an Autolite 4100 (1.12)
The tag reads C8AF AE with a date code of B 7M29.
The body of the carb has 8A AE stamped into the foot.

The internal parts:
Primary jets (51F)
Secondary jets (71F)
These seem big so it might be a 428 carb.

Primary booster (53 T2 6)
Secondary booster (F3A2 5)

Thanks for any and all help.

Per the Ford & Mercury Master Parts Catalogs (MPC), C8AF-AE is from a late ‘67, ‘68 & ‘69 full size Ford & Mercury Police Car with 428. Your’s from a ‘68 obviously by the date code. Jetting is correct.
