Blasting with baking soda (soda-blasting) will be the fastest and easiest method. ....It will not do any damage, and any residue can be washed away with water.

Harbor Freight sells some small inexpensive soda blasters.

Soda! thanks for that tip. They are a misery to clean up with all the irregular shapes and grooves to trap dirt.

Looks like I'm a day late on this? But I found a non toxic cleaner that worked remarkably well when I was rebuilding a motorcycle.
Soaking the carburator in pinesol /Water solution for a day or so removes the tarnish(may need a bit of brushing with an old tooth brush) and cleans internals very well. I found I only needed to use a wire to clean calcium/lime deposits from the jets. How the fuel gets calcium/lime to plug jets in it is beyond me?
Soda Blasting is also a good choice as Bruce mentioned. . If you do a google search there are instructions for making a homemade blaster on the net.
In fact here is a link I'm also going to post it in the mechaics section in case someone misses this post.. http://www.aircooled...p/soda_blaster/

That is not calcium and lime, that is oxidation.
We are seeing more and more of this as ethanol amounts increase n gasoline.
Once again, it is more important than ever to keep your small engine fuels treated with a product such as Sta-Bil ;)

Try using Bug and Tar remover on your Carbs. Mine cleaned up rather well. After you spray the Bug and Tar remover on the carb, clean the carb with Dawn dishwashing liquid, to help remove any greasy residue left behind.
