Lean idle. Rich cruise.
22* at idle is about half of what you would need with that cam. T/blades are open too far at idle; which is why backing out the mixture screws richens the cruise. You can use an adj vac adv unit to give another 18-20* at idle [ connect to man vacuum]. A 440 I tuned recently idles at 42* with very similar cam specs. Your engine is smaller so the cam will look 'bigger'.
