Lawn mower question

Is this a guessing game ? What's the prize ? Do we get any more information or hints ? I suggest that you place the mower at the curb with a sign on it - free to good home, ps: what is your address ? John T.

IDK, sounds like she's ready for the crapper.

Normally bogging it down like that, which you shouldn't do, will just stall it. But since you heard a crack and it's now blowing smoke, sounds like something bad happened internal to the engine. If it was anything other than that, it should self clear in a minute or two. How long was it running and smoking? Check the oil level? Not overfilled? On the other hand, I'm having a hard time imagining what stalling it like that would cause to fail that would produce the smoke.

It hasn't self cleared. I let it set for about 10 minutes, went out started it up, still blowing smoke. I don't hear any specific rattling, etc, but it loud anyway. It is about 6 years old, so I am leaning toward using it until it detonates and then go get a new one. It had bogged down many times over the 20 minutes or so I was using it before the weirdness started. Oil wasn't overfilled as I had changed it earlier in the summer and using it since then with no problems. THere are now little spots on the mower that look like oil being thrown off.

Overheated. Micro-siezed. Damaged cyl and/or rings. It's toast.

The first time I started my mower this year, it was smoking heavily. I found the filter was really dirty. Changing it stopped the smoke.
