How to clean a clogged gasoline carburetor

  • Check the condition of the spark plugs.
  • Drain or siphon the fuel from the tank.
  • Drain the fuel from each carburetor bowl plug. (If this part is inaccessible or out of reach, see the "Important Notes" section)
  • After draining the gasoline from the tank and carburetor, add Sea Foam and 8 ounces of fresh gasoline mix (1 to 2).
  • After putting the cleaning mixture into the fuel tank, pull the engine with the crankshaft/Prime/rope to draw the cleaning mixture into the carburetor.
  • Allow the engine to sit and soak for a period of time - overnight to 24 hours if possible, 48 to 72 hours if necessary.
  • Once the engine is started and running, SeaFoam in the tank will continue to dissolve residue as fuel is drawn in and through the carburetor.
  • When ready to run the engine under high load (normal engine use), add more fresh fuel.

IMPORTANT:If you are unable to drain the carburetor or tank of old fuel, remove the spark plugs and add a high concentration of Sea Foam and new fuel to the fuel tank. After removing the spark plugs, follow steps 5 and 6.
