You may find that the mating surfaces and gasket are bad on the intake manifold.

On my 611b, there is a spring-loaded gate on the choke plate to keep it from stopping the airflow entirely. It had broken off and was laying in the bottom of the air horn. I'm afraid the engine swallowed the spring but didn't seem to hurt anything, dunno why not. But the choke won't kill the motor entirely without it, just make it cough and smoke. Good idea to pull the carb and look even if that's not it. Carb problems are almost ubiquitous on old machines that sit a lot. I habitually shut off the gas and let mine run dry when I put it away, seems to at least help.
