I haven't run mine in about 2-3 years. Motor started dieing out after 30 seconds of running. Pulled the motor changed the carb, changed the gaskets, changed the gas, changed the plug. Then finally I just gave up. Read a post about a year later about someone having the same issues. Turns out it was the fuel tank gas cap. The stock rubber flapper had hardened and caused vapor lock. Still never fixed it. By now all the tires are rotten.
Just pulled mine off the shelf and started tearing it apart to clean and rebuild. Haven't run it in about 6yrs, figured it was time. Got my buddy that bought my first one from me tearing his apart too. We will be ordering parts soon!
