Why doesn't my Benchmark 209CC start or runs roughly?

If your Benchmark Pressure Washer's engine doesn't start or runs roughly, several factors could be at play. First, ensure the engine power switch is in the ON (I) position. Next, check the fuel level and fill the tank with fresh, regular gasoline if it's low or stale. A dirty air cleaner can also cause issues, so clean or replace it. Make sure the spark plug wire is securely connected to the spark plug, and replace the spark plug if it's faulty. Additionally, verify that the oil level is adequate and add oil if necessary. Depending on whether you're starting the engine cold or warm, adjust the choke lever accordingly. Finally, the carburetor might be clogged and require cleaning, or excess water pressure in the pump or hose may need to be released by squeezing the trigger on the gun.
