Engine starts easily but dies after a few seconds.
Possible causes:

  1. Fuel tank is empty or shutoff valve is closed, or fuel line or fuel tank cap vent is clogged.
  2. Carburetor is overchoked.
  3. Carburetor is improperly adjusted or needs service.

Remove the Muffler and Check the Exhaust Port and Muffler. They could be Stopped up. Also could be a Valve problem too. Set the High Speed Fuel Mixture Screw to 2 instead of 2 1/2 turns. Hope this Helps.
