  If your Generac Power Systems Portable Generator engine won't start or runs roughly, several factors could be at play. Here's a breakdown of potential causes and solutions: * Ensure the fuel shut-off is turned ON. * Check and clean or replace the air cleaner if it's dirty. * Verify that the fuel tank has gasoline; if not, fill it. * If the gasoline is stale, drain the tank and refill with fresh fuel. * Confirm the spark plug wire is connected to the spark plug; connect it if it's not. * Replace the spark plug if it's bad. * Drain the fuel tank and fill with fresh fuel if there's water in the gasoline. * Adjust the choke knob to the 'No Choke' position if you've over-choked the engine. * Ensure the oil level is adequate by filling the crankcase to the proper level.
