Q:

Lawn tractor will not start. Model number (917.2736401) 917.2736401

A:

Thanks for the inquiry and for using SearsPartsDirect.com.
I was not quite clear on your details, I think you may have made a typo in the second to last sentence. If you turn the starter key off, it will shut off the engine, so that sounds normal.
Since you've verified spark, and the engine turns over, I suspect the issue is with fuel. I would remove the inlet fuel line going to the carb and turn the key to 'Start.' From there, you should see fuel coming out of the line from the fuel pump. If that's the case, then we can isolate the issue to the carburetor or fuel solenoid. 
To check the fuel solenoid you will need to remove it from the engine. Next, you will need a piece of wire to connect it to the battery. Place the case of the solenoid against the negative post on the battery. Then connect the wire from the solenoid to the positive post on the battery. Once the connection is made, the end of the solenoid should retract. If it does not retract, the solenoid is defective. 
If the solenoid checks out, I would bet the issue is internal within the carb. I would pull the carb and do a thorough cleaning on it and pay close attention to the main jet and the needle/seat area. You could have a sticking needle and/or a fuel logged float that is not allowing a free flow of fuel into the carb. Have a fuel can of carb cleaner, a wire brush, and a bread tie wire to poke through the main jet to clean it. Be very thorough with the cleaning because if you leave varnish behind, there is a strong likelihood it will become dislodged after assembly and reclog the jet. If any of the components look worn, you can purchase the carb rebuild kit for the engine, the part number is 697241.

Thank you for your question. I am sorry you are having a problem with the tractor. If the engine will not turn over, I recommend removing the spark plug and then turn the key to the start position. The will ensure the engine is not seized up. If the engine will turn over with the spark plug removed, I suspect the valves may be out of adjustment. If they are not adjusted correctly, the compression release will not work and the starter is not strong enough to turn the engine over. To cure this problem the valves need to be adjusted. I found a great video that show how to adjust the valves on the engine. Click here to watch the video. This is part one of two. Be sure to watch both videos. If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a  Sears technician.  Here is a link for the website:  Sears Home Services.   I hope this is helpful. Please let me know if you need further assistance.   Thank you for using Manage my life. Mark T.

Pull the black (kill) wire from the ignition coil and then check to see if you have spark. If you do not then the coil has failed and you'll need to replace it. If you do have spark then there is something in the kill circuit that's causing the problem.

Most tractors will not spin over if a safety switch has failed. The best way to track down the problem if you have spark with the kill wire removed is to follow the wire back from the ignition coil and check for any shorts and if it goes through any safety switches, check them with a meter to see if they are working as they should.

Thank you for using Manage My Life!
