Why won't my Yamaha YG5200D Portable Generator engine start?
- JJustin WilkinsonAug 5, 2025
If your Yamaha Portable Generator's engine won't start, there could be several reasons: * No fuel is being supplied: Ensure the fuel tank has fuel and that the fuel line and fuel cock aren't clogged. Clean them if necessary. * The carburetor might be clogged: Clean the carburetor. * Insufficient oil: Add engine oil. * Poor spark: Remove carbon or wipe the spark plug dry. For issues with the ignition system, worn piston/cylinder, consult a dealer. Also, make sure cylinder head nuts are properly tightened, and replace any damaged gaskets.
