Autolite 4300 Carburetor C9ZF-F

QKSLVER:
I am looking for a restored Autolite 4300 carburetor, C9ZF-F, for a 1969 Mustang 390 Mach 1 with an automatic transmission.  Given the fact these aren't as popular as the Holley counterparts, does anyone have a recommendation on the best place to find one?  Most of the vendors I see selling restored carburetors only seem to carry the Holley.  Thank you in advance for your assistance.

Of course you can wait around and hope a restored one shows up. Since that carb is not in high demand most that restore and sell will not put the time and money into it to sit on a shelf. Your best chance is to find one used and have it restored. best of luck on your search.

For some reason carb rebuilders have a hard problem getting 4300's to run right. At least from mine and just about everyone I know experience. If anyone has FIRST hand experience with someone who can rebuild a 4300 and make it run properly there are a lot of us out here that would like to know . Many say that they can but when you get the pretty restored carb it doesn't run right or runs ok for a week and then goes to s#!t.  Many enthusiasts just give up trying to get one to run right and run a Holley.

Ain't that the truth. I took me over 10 years to get these Webers to run right on my VW engine. The experience got this one offf a 66 done in a day. See attached.

If you do get the one you need and it does need a rebuild, scratch some "code" on the underside as an ID and take a picture of it. A couple of members of my Mustang club sent their carbs out to get rebuilt only to get something else backJim
