Yeah, but you won't run out of lubricant 'til you run out of gas, so when the lube stops, so does the engine. That assumes it's a 2-stroke, of course.
My post on the fuel disconnect was not so much where it was disconnected, as how. On my Honda (40hp 4-stroke), there was a dry-break clip-on fuel fitting at the motor to hose connection point. Disconnecting the hose and waiting for the engine to die would not empty the carb bowls, as the line drew a vacuum well before that. To empty the bowls, you had to sit there and hold the spring-loaded dry-break ball bearing in with a pointed object. Took a while to run dry, too.
