    How to start a Chicago Electric 97906 that won't start?
    • M
      Marc RossJul 31, 2025
      If your Chicago Electric Portable Generator's engine won't start, it could be due to several fuel-related issues. First, ensure there's fuel in the tank and the fuel valve is open. If the engine is cold, make sure the choke is in the start position. Old or low-quality gasoline can also be a culprit, so use fresh 89+ octane unleaded gasoline. Try priming the carburetor if your generator has a priming bulb. Additionally, check for and clean any dirty fuel passageways or a clogged fuel filter. If the carburetor needle is stuck, gently tap the side of the carburetor float chamber. If there's too much fuel, turn the choke to run, remove the spark plug, pull the start handle to air out the chamber, and then reinstall the spark plug and set the choke to start.
