Craftsman mower will not start

I used the mower about two weeks ago before the rain set in around here and it ran fine - I turned it off in my backyard and it would not crank.

It is a 917.256550 with a Kohler 15 Hp Cmd-L 5&3 engine model CV15s PS-41519.

I changed the plug but notice that it is not firing when I have it out of the head.

Any help would be helpful.

Possibly you have a safety switch or ignition module problem. Remove the engine blower housing (cowl) and remove the wire plugged in to the coil. Start engine and check for spark. If you have spark the problem is in a safety switch or ignition switch.

If engine starts the ignition switch will not shut the engine off. Be prepared to remove plug wire or ground plug.

You can download an engine manual here:

The manual below has an excellent chapter on troubleshooting safety switches. Jumper wires shown in the manual can be fabricated at home.

Many of the kohler equipped craftsmans had relays under the dash area, usually under the gas tank towards the right side of the mower under the dash. One of these relays can cause the engine to not spark, especially when it gets wet. If it got rained on, this would be a good place to check.

Pulled it all apart finally and got it running. Seems to have been the saftey for the mower blades when they are engaged. I guess it was stuck - fired right up when I unplugged it - I hit it a couple of times with a screwdriver and plugged it back in and it still cranks!
