The engine on your lawn mower has a form of automatic choke on it. I suspect something is sticking in the automatic choke mechanism causing the engine to die and not start back.

I suggest you remove the blower housing from the top of the engine and inspect the automatic choke. The automatic choke is attached to the air vane governor and also has a thermostat that senses exhaust temperature. If you move the linkage back and forth you should see the shaft on the choke plate in the carburetor rotate to open and close.

These parts are under the warranty of the engine and you can take the mower to a Sears Repair Center and they will repair the mower free.

Hi Jimmy, thanks for your reply. Could you include some directions as to how I might be able to get the choke unstuck myself? I'm not sure what you mean when you say blower housing and air vane. Would that exist on a mower or more likely a leaf blower? I'd rather not loose my mower for two weeks while Sears sends it out and I'd like to try and fix it myself because of this... Thanks!

Hi Jimmy - Thanks for that. I followed the video you posted and did not find the choke arm to be in the wrong position or pulled over to the wrong side of the arm. I do think we might be on to something though. Upon starting the mower the choke is in the open position and remains open throughout. It never seems to close. When the engine starts to sound like it is going to stall I push the arm towards the center of the engine closing the choke. It runs doesn't run well, but it seems to keep the engine running. Does this tell you anything? I have also posted a video of this on YouTube so you can see what I mean. I am attaching the link as well.

Thomas, one thing the video wasn't real clear on is the arm that opens and closes the choke has to move very freely. If there is friction on the arm it won't open and close the choke properly. If the engine isn't running smoothly, the carburetor probably has some blockage. I am sending another video showing how to clean the carburetor. Sometimes cleaning the carburetor doesn't remove the blockage and the carburetor has to be replaced. The choke should be closed when the engine is cold. I suspect the air vane arm is not moving properly to close the choke. When the engine starts, the air from the flywheel vanes causes the air vane to move over opening the choke. You need to figure out why the choke is not opening and closing properly.

Hi Jimmy - I already cleaned the carb as mentioned in my original post. Now that you mention it, I do feel like the arm moved more freely when the unit was taken apart. I didn't get the link from you on cleaning the carb, but please send it over so that I can be sure I did it properly. You say that the choke should be closed when the engine is cold which confuses me. Because since it is always open why does it start so well open? Why does closing it once the engine is warm keep the engine running? This seems to be the opposite of what I would expect given your last post.
