Dump enough fuel stabilizer into the fuel for it's volume, according to the manufacturer's recomendation. Remove prop and start the motor on a flusher device and warm her up, allowing the stabilized fuel to get to the carbs. Now while running at idle, spray some fogging oil into the three carbs, until you get good smoke. Then shut her down or stall her. Turn off ign key, disconnect battery, pump grease into fittings, gease steering rod, change gear oil.
