  There are several reasons why your Craftsman Portable Generator might not start. Here's what to check: 1. Ensure the engine switch is in the on (I) position. 2. Make sure the fuel valve is in the on (I) position. 3. Check the oil level and fill the crankcase to the proper level, or place the generator on a level surface. 4. Inspect the air filter and clean or replace it if it's dirty. 5. Verify that the fuel tank is full. 6. Confirm the spark plug wire is connected to the spark plug. 7. If the engine is flooded with fuel, wait 5 minutes and try re-cranking it.
