Model #917388861 Craftsman walk behind lawnmower, gas

Question and Answers


lawn mower 917388861 starts for 2-3, dies.


Thank you for your question.

If the engine will run when you spray along the intake and behind the carburetor, the engine has an air leak. What is happening is air is entering the engine without mixing with fuel. This causes a lean condition and the engine stalls. When you place the cloth behind the filter, it gives the engine more fuel and it will continue to run. I recommend inspecting the intake tube and the o-ring where the carburetor mounts. If the tube is cracked, the tube has to be replaced. I also recommend replacing the o-ring at the same time. The part for the mower can be ordered from the following link. Craftsman tractor parts
