I took the air cleaner off so I could make a close comparison of my carburetor with pictures of a potential replacement.
It had more stuff attached to it than I knew about. When I looked it up in Chilton and Haynes I found descriptions of various parts in different places, no unified explanation.
There’s a hot air intake system, which has a switch mounted inside the AC, connected to 2 thin hoses, 1 of which goes to the HAI diaphragm.
A large hose connected to the bottom of the AC goes to a rubber or plastic canister under the AC - some kind of vapor recovery system?
Another thin hose on the bottom goes somewhere; another thick hose goes somewhere.
Is there a single place I can find a description of all this stuff? I looked at a couple of auto parts places in hopes of finding a manual for a replacement AC, but they don’t sell them.
