Put a fuel petcock on the genset and shut it down by running the carb out of gas. You'll never have to clean out the carb again.

Another genset tip: if it's got a flat head (non-OHV) engine, check and adjust the valve lash regularly. Running those old style engines at 3600 RPM makes the valves recede pretty quickly.
