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.
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.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
