I have a Craftsman 10-Hp Tecumseh engine riding mower that will not restart. I followed the winter storage and spring tune up procedures - change spark plug, oil and air filter, charge battery. etc, siphoned as much of the fuel stabilizer out of the fuel tank as possible, and filled the tank quarter full. I then started and ran the engine for 5-minutes, and then shut it down. It sat in the garage 2-3 weeks until time to cut the lawn. PROBLEM: IT will not "turn-over" when I try to start it up. The electrial components look to be OK, but there is no turn-over. ANY and ALL suggestions are appreciated.

 

It sounds like the battery is dead or one of the safety switches is engaged when it shouldn't be.
I would charge the battery back up and see what happens.

 

Does it do anything or make any sounds?

First I would check to make sure the cable connections to the battery are clean and tight. Next I would look at the battery. Take it to an auto parts store and have them test it under load because even a bad battery can show 12+ volts at rest but can't deliver the surge of current needed for starting.

 

Tryed to jump start it off of the car battery yet?

 

Remove spark plug and see if it will turn over, cylinder could be full of gas, which means your carburetor could be leaking fuel into the engine. Also recheck the oil if this is so. Change the oil if gas has gotten into oil. If no gas and it still won't crank, check the fuse which is near the solenoid. Good luck.
