I have now loaded MOST of the factory Carter service documents on my website. These are the generic instructions by carburetor type (i.e. W-1, WCFB, AFB, Solid fuel Thermoquad, etc.).
Some of the later documents are large (in Adobe pdf format), and will take several seconds to load; BE PATIENT!
And while all of these documents were copyrighted, I have written authority from the Carter Carburetor Company to copy them.
Still looking for the documents for the AVS (maybe Carter didn't figure the AVS was worth servicing  )
Here is the link:Â Â http://www.thecarburetorshop.com/Carter_service.htm
For those of you in love with the Carter/Webber progressive two-barrel, the correct type is the Carter type 740, and the factory service manual is loaded.
