Small Engines (Lawn Mowers, etc.): John Deere LX178 lawn mower, john deere lx178, fuel tank cap

Question
My John Deere LX178 lawn mower starts but after mowing about 5 minutes it spits and sputters and shuts off and will restart but continues to spit and sputter and will not run continously.

Answer

If 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.
