need help with my lawn mower, for some reason it will start for about 10 seconds but then dies andy one know what the issue could be? 917379500 model #


The engine is probably starting and running on the gas you pumped into the carburetor venturi with the primer. It sounds like the carburetor is stopped up and not supplying gas to the engine.

Be sure the gas in the engine is less than 5 weeks old or has fuel stabilizer in it. Remove the carburetor bowl and clean it. This will ensure the carburetor has fresh fuel in it. Old gas will cause the engine to start, but not run.

If cleaning the bowl doesn't help, you should replace the carburetor.
