Cleaning out idle circuit on Edelbrock AFB

Guys,
I'm taking the top off my Edelbrock AFB to adjust the floats and clean the needle/seat. While I am at it I also want to remove the 2 idle mixture screws to clean out the idle circuit. I don't have access to compressed air right now but I do have a spray can of carb cleaner. Can I just spray some carb cleaner into the idle circuit via the mixture screw holes? Or will that cause more harm than good?
