I'm working on a motorcycle carb here but the question could apply to tractor, cars, or trucks with carburetors so here goes.
I'm reading an article on line that says that a vacuum leak can happen between the carburetor air intake throat and the airbox (air cleaner). For example, visualize an air cleaner that has a rubber boot tube that hooks up to the intake throat of a carburetor. If the boot has a hole or crack in it, can this result in a "vacuum leak"? It would be my understanding that a vacuum leak would have to be between the carburetor and the engine (not between the carb and the air cleaner). If that could be a vacuum leak, then how could an engine even begin to run with the air cleaner removed?
