I honestly have no idea what jetting it is. I want to say it’s whatever the factory put in a 383 67 barracuda Carter but I don’t know if someone played with it over the years. It does smell rich and I got the car running after years of dormancy and did nothing to the carb other than hose it down with spray cleaner. I’m still somewhat amazed that it doesn’t leak. The choke doesn’t work and one day I found the linkage screw for the accelerator pump sitting on the manifold after I’d been driving it for a bit. I do intend to pull it out and have it gone through by a shop but I haven’t gotten there yet.
