Over the Christmas holiday, I restored the Bing carburetors. A restoration is a bit more work than a rebuild since the goal is to restore the finish to factory new condition as well as replace worn parts and all the O-rings and gaskets. Much of the time invested is in cleaning and polishing all the parts. You can access the web page about this using the this link:
which is also on the list of pages to the right. I’m using BMW parts subsystem numbers for the rebuild blogs so you can correlate the procedures with the parts. You can see the numbers on Hucky’s R75/5 parts ordering page.
Here are some before and after pictures.
