Default Vacuum Advance?

Engine won't idle down after letting off the gas. If I give it a quick kick it will usually drop down. Last time out it was bogging and jerking when cruising when hitting the gas. I think the vacuum advance is sticking. Haven't pulled it apart yet but wondering what's good to clean it up and get it working. It's a GM HEI distributor.
