It should run just fine with that hose removed. Might indicate a vacuum leak around the manifold or carburetor. Once you find and fix that leak, then check your air cleaner as it should not be giving you that much choking action.
With it running spray around the edges of the intake manifold and the carb connection with propane. When the engine changes, you have hit the leak.
