Craftsman won’t restart

My self propelled push lawnmower runs great till it gets hot. When I turn it off to empty the bag and restart, it will not. It seems like a vapor lock. But it’s been running great for 5 years. It’s stored in a heated garage during the winter.

Sounds to me like your ignition coil is going out. I could be wrong in saying this, but I doubt it would br a vapor lock since it runs just fine when it is running. it only gives you issues when you turn it off. If you had a vapor lock, it would run erratically for a few minutes before it dies. Good luck!

Your magneto is failing. They grow weak when heated when they go bad. Lawntoro is right.

Ditto the above but another idea: How old is the mower? If it's newer and has the automatic choke I've read about some owners having a hard time restarting after a brief shut down due to the thermostatic element (usually attached near or on the muffler) cooling faster than the engine, being the muffler is sheet metal I guess, so what happens the choke kicks in but the engine is still too warm for such a rich mixture. The thermostat should have a link wire running to the choke arm on the carb if yours has this.

if it's an older L head or flathead Briggs with the suction feed carb (carb mounted to tank) these can be notorious for hard restarts, years ago a neighbor had one on a B&S 3.5 hp and it wouldn't restart after emptying the bag, so he just took a drink break and 20 min to 1/2 hr later it started on one pull, I've also had that with an old L head of mine.

Good luck, hope we can help here, this a knowledgeable group.

Try removing the gas cap and then putting it back on. If it has a Techumseh engine they had issues with gas caps causing pressure/venting issues
