What to do if my Storm Cat Portable Generator engine stops suddenly?
- D
  Donald PopeAug 16, 2025
  If your Storm Cat Portable Generator engine stops suddenly, consider these potential causes: * The fuel tank might be empty or filled with impure, low-quality gasoline or an improper gasoline/oil mixture. Refill the fuel tank with fresh 87+ octane unleaded gasoline in a 50:1 mixture with oil, ensuring the gasoline contains no more than 10% ethanol. * A defective fuel cap could be creating a vacuum, hindering proper fuel flow. Test or replace the fuel cap. * A faulty magneto could be the issue. Have a qualified technician service the magneto. * The spark plug cap might be disconnected or improperly connected. Ensure the spark plug cap is securely in place.

How to start a Storm Cat Portable Generator that won't start?
- C
  Crystal WilliamsNov 12, 2025
  If your Storm Cat Portable Generator's engine won't start, here's what to check: * Make sure there's fuel in the tank and the fuel valve is open. If not, fill the tank and open the valve. * For a cold engine, ensure the choke is in the CHOKE position. If not, move it to that position. * Verify you're using a 50:1 gasoline to oil ratio. If not, correct the mixture. * Ensure you're not using gasoline with more than 10% ethanol (like E15, E20, or E85). If you are, clean the fuel system, replace any damaged components, and switch to fresh 87+ octane unleaded gasoline in the correct ratio. Also avoid old or low quality gasoline - use fresh gasoline instead. * If the fuel passageways are dirty, clean them using a fuel additive. For heavy deposits, further cleaning may be needed. * I...
