To start a flooded 2-stroke outboard engine, follow these steps: First, disconnect the fuel line to prevent more fuel from entering. Next, open the throttle fully while in neutral to allow maximum air flow. Then, pull the starter cord a few times to clear excess fuel. After a few pulls, reconnect the fuel line and attempt to start the engine normally. If it doesn't start, check the spark plugs and clean or replace them if necessary.**
