Do we know if there is already a write-up on how to remove the butterfly assembly in order to clean it and lube it?

I feel my idle stumbles at times because things are not rotating easily enough nor springing back to their rest position. I would like to get in there and clean things up and lube the pivot points of the butterfly valves and throttle linkage as well as the two main springs.

If someone knows of a step by step process for removal indicating what comes off and in what order, I'd love to look it over. Not likely the hardest thing to figure out, but thought it was worth asking about. Service manual perhaps? Current version with photos would be ideal.
