Uhhh, nope--not on a 914. The cannister has three hoses that go to it. One large hose comes from the fan shroud. Air that has been pressurized by the fan is pushed into the cannister. It goes through the cannister, and returns to the air cleaner through the other large hose. The small hose comes from the "expansion chamber" which sits on top of the fuel tank. This is how the gasoline vapors get into the cannister.

That's all there is to it. No connection to the throttle in any way.
