Re: IML: keeping the original Carter carburetor



Chris, a simple way to verify too lean a mixture, would be to warm up the engine, make sure the choke is open. Then run the engine at the RPM it seems to have problems at, I'll bet its between 1200-1800 rpm.Thats the range the carb goes from low speed idle circuit, to hi-speed jets. Run the engine at the speed that is missing- running poorly, then slowly close the choke blade, if the engine runs better, and speeds-up, then your lean. If the engine slows down,and runs worse then you could be too rich already, or you have other problems, which could still be carb related, or ignition. Don't sell the spark plugs short, even if they're fairly new, they can also be a problem.If they are fouled from old gas, carb problems, and oil fouled, without being driven enough, you can CHASE your tail till pigs fly and never get it right.Don't ever assume you have only one problem, that will help you through the problems.Ya'll have a nice day, Dave.

Would too small of jetting of my AFB cause my symptoms, missing irratically at a steady speed(no load, seems much better under load)? I don't seem to get much reaction with the idle screws beyond a certain point. I could back them all the way out with no change.

The most important factor, to a successful rebuild, is the amount of contaminated fuel the carb has been exposed to. We've rebuilt AFB, AVS, TQs, and HOLLEY'S, that have burned enough fuel to take the average Imperial to the moon, and half way back.The most damaging contamination is water. If you disassemble the carb, and its full of aluminum oxide ( white dust, and goo), then your headed for trouble.The standard varnish deposits can be handled with a good soak, and to clean the small passages,like the venturi cluster dip tubes, we found a welding tip cleaner to work really well.(and a compressed air blow out) Don't forget the fuel that these carbs were calibrated for no is longer common, that requires re-jetting and some fine tuning to get proper performance. We found that an increase of jet size, between 2-5 richer steps works fine.The fact that some have converted to the Edelbrock carb, and have been satisfied, is basicly from richer jetting, not to mention the electric choke.Ya'll have a nice day, Dave.
