I had to sync my carburetors up on my 300F. You use a tool called a Uni-Syn. You only need one as you do each carburetor separately. It measures the airflow through the carburetor and you want them to match. They are typically used on foreign cars with smaller carburetors so the tool does not fit the Carter AFB carburetor air horn directly. What I found was that a standard 1 pound cottage cheese or sour cream container fits the top of the carburetor perfectly and then you cut a hole in the bottom of the container for the Uni-Syn to sit on. I don’t have a picture of the Uni-Syn on the carb but this shows the container fitting over the carb. Also a handy thing to have around if you’re working under the hood with the air cleaners off to keep stuff from getting in the carbs.
Very good points, John. I just sent Scott at Harms Auto a message. He isn't cheap, but since he is good with ram setups I think it is worth it. After the base price of $200-250 per carb, you are paying for the experience. Normally, I like to do everything myself and have been tempted to rebuild them, as I have rebuilt a few carburetors myself, mostly successfully. However, thinking about trying to balance them myself and futzing around with them and never having the car run perfectly seems like a distinct possibility, even though I have the 300J supplement manual. I think I will request a step by step from Scott to set up and tune them (possibly rebuild as well). If i do get that information, I can pass it along for future reference.
Thanks for the (nearly instantaneous) help!

This is a really important question I think . How do we know who is good, or in my case , still good? Some of the older big names who routinely did a great job (why name anybody...) now have young kids putting carbs together , often all wrong .... that business is about gone in a commercial sense . And my former place had so many complaints —- I hear they now just sell kits. Nothing is worse than a poor rebuild, factory things messed up .. in my case , the Fit of throttle plates. Jamie has seen same thing, even worse, parts from the two carbs all mixed up . Shows guy who did it was clueless.
