Why won't my Snapper 3500PSI Pressure Washer engine start or runs rough?

If your Snapper Pressure Washer engine won't start or runs rough, there are several possible causes: * Ensure the fuel valve is in the “On” position. * Make sure the rocker switch is in the “Run” position. * The air cleaner may be dirty; clean or replace it. * Check and fill the crankcase to the proper oil level. * Ensure the fuel tank has gasoline; if not, fill it. * Drain the gas tank and fill with fresh fuel if the gasoline is stale. * Connect the spark plug wire to the spark plug. * Replace the spark plug if it's bad. * Drain the gas tank and fill with fresh fuel if there is water in the gasoline. * If overchoking, open the choke fully and crank the engine.
