Boy that is a good one , guess you have checked the key on the flywheel it is almos tlike a fuel issue , do yo uahve some startin gfluid or even carburator cleaner fro mwalmart ?? if you spray the intake and it keeps running the carburetor might be clogged.Have you replaced the cap on the gas stank A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall. If the carburetor is clogged, try cleaning it with carburetor cleaner. It most postively sounds like a fuel issue.
That is a 2 stroke engine so you are using 2 stroke oil/gas mixture?
Do not carry to the junk yard will make a good trotline weight ,just kidding!
