Thank you for your question.  I am sorry you are having problems with your mower. Usually when this happens, it is because there is debris floating around in the carburetor and main jet. I recommend cleaning the carburetor first. To clean the carburetor remove the spark plug wire and tip the mower onto its side with the air filter up. Behind the air filter, you will see the carburetor. You have to remove the main jet from the bottom of the carburetor. I have marked it in the image below. Once the main jet is removed, you can take the float bowl off. Make sure you do not loose the rubber o-ring. Set the o-ring aside you do not want to get carb cleaner on it. Clean the inside of the float bowl with carb cleaner and a scotch brite pad if needed. Then use the straw that came with the carb cleaner to spray up into the carburetor where the main jet came from. After it is flushed out you can let is dry while you clean the main jet. The main jet has hole in it. Push a bread tie wire into the small hole of the main jet and flush it with carb cleaner. After it is clean, you can reassemble the carburetor. Make sure you put the o-ring on first. It has a step it should sit on. Then install the float bowl and main jet. Tip the mower back over and put the spark plug wire back on. Try to start the mower without priming first. Sometimes it does not need priming because it was tipped over. If the mower does not start, go ahead and prime it. This usually cures the problem you are having.  I have found a video that will give you more confidence in doing this repair. Please click here to watch the video . The engine is not the same as yours but the parts are similar.  _Note do not get the carb cleaner in your eyes_  Please let me know if you have any other questions.    If you do not feel confident repairing this problem yourself, then you can have it repaired by a Sears  technician.  Here is a link that will provide the nearest drop-off locations:  Sears Home Services   Thank you for using Manage my life.  Mark T.

Q:

The mower sat for years, and won't start. What should I do?

A:

I think you need to rebuild or replace the carburetor. You can order a kit to overhaul the carburetor (part number 632760B $20.00), or a new carburetor (part number 640262A $70.00).

If you overhaul the carburetor you need to let it soak in carb cleaner several hours. Run a soft wire through each fuel and air passage inside the carburetor and blow them out with compressed air.

If the inside of the carburetor has a white substance built up on the metal of the body you should replace the carburetor. This residue is from the water in the old fuel attacking the metal and will continue to stop up the fuel passages. It can't be corrected.
