There are two online communities dedicated to Honda twin-cylinder motorcycles - including the CB350 - hondatwins.net and hondatwins.com.  The former is quite active while the latter is all but dead.

I prefer the Clymer manual over the Haynes manual but having at least one of these is a necessity.

Here's a CB350 blog that features a detailed carburetor rebuild walkthrough. You can also check out benmiranda.com/my-honda-cb350 for more information on CB350 carburetors and jets.

For DOHC models, check out cb750c.com. For earlier models, try sohc4.net. Either or both of the Clymer or Haynes manuals are strongly recommended.
