Nah, they are not meant to come off easily. They prevent emissions "tampering." In the day, techs would get new ones if the idle mixture needed adjustment. Just break them and adjust to "best lean idle." IIRC new caps used to come with the rebuild kit - maybe they still do.
Don't bend the idle screw - I'd get in there with my cutters and nip at them until they come off. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
