Marc, You are on the right track with changing the main metering jets. But the fuel with 10 percent alcohol will always be troublesome with a carb. If you can get a tank full of pure gasoline just as an experiment.
Oh there are more than one Charlie, Charlie NY is a great guy for carbs and distributors. Old point ignition or petronics probably won't act much different if the fuel isn't up to old standards. High test isn't necessary, dont know about the additives.
