The first thing you need to do is change your engine size. A 65 Beetle originally came fitted with an engine that was 1192ccs in size. Aircare allows you to truncate, so next time you get tested, tell the guy right at the start that your engine size is supposed to be listed as 1.1 liters. If they don't believe you, they can look it up. This will give you more headroom on some of the cutoffs.
Your high CO% means your idle jets are too big. You should pull them out and see what size they are.
Consider this, you now have one year to get the engine running perfectly so it will breeze through aircare all the time. Also, by putting in a smaller idle jet, you should see better mileage while at the same time have an engine that makes more hp.
