Q:

lawn mower #917385131 will not start 917385131

A:

Thanks for the inquiry and for using SearsPartsDirect.com.
Sorry to hear of the issue you're having with the push mower not starting, I know how frustrating that is to have occur. 
It sounds like the issue is going to be either spark or fuel. To rule spark out, pull the plug and reattach it to the boot. With a helper ready to pull the rewind starter, ground the base of the plug to the cylinder. Have the helper pull the rope and check the base of the plug for spark. If there is spark, then we can focus on fuel.
Even though you are methodical with the fuel, the new ethanol mixtures are tough on these carbureted engines. I would pull the carb and do a thorough cleaning on it with carb cleaner, a wire brush, and a bread tie wire to poke through the main jet to clean it. After cleaning, douse liberally with carb cleaner. You may just have a partially clogged fuel jet that is starving the engine of fuel. 
Hope these suggestions help and thanks for using SearsPartsDirect.com. We appreciate your business.

Since I completely changed out the spark plug I should be able to go ahead & rule that out shouldn't i? Or should I still do as you suggest? Can you tell me exactly how to get to the carb? The diagram on the website doesn't show it. Thank you.

That test isn't for the spark plug per se, it's for the spark module. Simply changing the plug doesn't make spark, that comes from the spark module. I would recommend following the test to properly rule it out.

Hi Ms Balboa, does your mower stall when the airfilter is removed? Can you keep it running with the primer? How old is the gasoline? Thanks for the question.

By the symptoms of what the mower is doing I believe the problem is a dirty carburetor. Most likely, the carburetor’s main jet needs to be cleaned. I found a video that will instruct you on cleaning the carburetor. If you do not have carburetor cleaner can be purchased from any auto parts store. In the video, the technician replaced the float bowl. You will only need to replace the bowl if you can not get it clean with carburetor cleaner and scrub pad. I recommend only replacing the gasket only if it is torn. Most of the time cleaning the main jet is all that has to be done. If the engine

Make sure the fuel you are using is no more than 5 weeks old. fuel older than 5 weeks starts to break down and does not burn as well. If you need further information, please submit more details.
