  If your Guardian Portable Generator engine won't start or runs roughly, several factors could be the cause. Here's what you can check: * Ensure the air cleaner is clean; if dirty, clean or replace it. * Verify there's gasoline in the tank, and if it's stale, drain and refill with fresh fuel. * Confirm the spark plug wire is connected to the spark plug, and replace the spark plug if it's bad. * Check for water in the gasoline, draining and refilling with fresh fuel if necessary. * Adjust the choke knob to the 'No Choke' position if overchoking is suspected. * Ensure the oil level is adequate, filling the crankcase to the proper level if low.

  If your Guardian Portable Generator's engine runs but there's no AC output, start by resetting the circuit breaker. Then, check for poor connections or defects in the cord set and repair if needed. Ensure the connected device is in good working condition by testing with another device. If these steps don't restore AC output, there may be a fault in the generator itself.

  Your Guardian Portable Generator engine might shut down during operation due to a few reasons. First, check if you're out of gasoline and fill the fuel tank if needed. Also, verify the oil level and fill the crankcase to the proper level if it's low. If these aren't the issue, there could be a fault in the engine.
