    Why won't my Firman Portable Generator start?
    • C
      Christopher HillAug 3, 2025
      Your Firman Portable Generator might not start due to several reasons. Check the oil level and fill to the proper level, ensuring the generator is on a level surface. Make sure you have enough fuel, either gasoline or propane (LPG). Inspect the spark plug and replace if it's bad, ensuring the spark plug wire is connected. Also, check the fuel filter for clogs or dirt and clean or replace it. If using propane, ensure the cylinder knob is fully open. If the battery is low, start the engine in "GAS" position, and consider charging or replacing the battery. Lastly, adjust the choke position and clean or replace the spark arrester if clogged.

      If your Firman Portable Generator lacks power, start by checking the load and adjusting it if it's too high. Clean or replace the air filter and fuel filter. Also, clean or replace the spark arrester. Ensure the generator isn't overheating by checking for air restrictions and moving it to a well-ventilated area. Finally, adjust the choke position.

    Why does my Firman Portable Generator bog down under load?
    • E
      Eric StoneAug 22, 2025
      If your Firman Portable Generator runs well with no load but bogs down when you connect loads, the fuel filter may be clogged or dirty, so clean or replace it. The fuel line (gasoline or LPG) might also be clogged, so clean it. Check if the generator is overloaded and adjust the load accordingly. Additionally, the spark arrester may be clogged, requiring cleaning or replacement.

      Angela McmillanAug 27, 2025
      If your Firman Portable Generator engine hunts or falters, the fuel filter may be clogged or dirty, so clean or replace it. If you're using propane (LPG), ensure the tank is full. If you're using gasoline, check the fuel tank level and refill if low.
