Stihl fs66 problem

New to the forum and looking for some expertise.

I have an older Stihl fs66 brushcutter that will only prime with a shot of fuel/carb cleaner directly into the carb. New carb, fuel lines, gaskets. Impulse orifice is free and clear. When I do prime this way and get it running, it idles high. Exhaust is free and clear. I'm stymied.

Try adjusting the carb mixture screws CC to richen the mix.

You may have to go several turns out.
