Ya... I was hoping I might still be able to rebuild it but I think that's out of the Q now.. heh

Nice shot showing the chunk from the cylinder wall missing.

The question I have is was that piston down since I had it? I only used it a few times, seemed to run decent.. I cut a really bad yard with it most the way through. I did put new plugs in it when I got it. I pulled them out last night and was surprised. The one was black and sooty looking. I can deal with that. The other (with broken rod) was completely clean sans a little bit of oil on the tip. I mean spotless looking. That tells me that it was working on one cylinder from the day I got it, then maybe while cutting that lawn. the rod got pushed in the wrong direction, shattered the rod and the wall.
I don't know...

Not enough info to draw any conclusions...
Did the camshaft break....
Was the engine smoking....
1 rod is still connected...if it was running like that ....in tough grass...
You would have 2 broken rods....

I'm gonna guess you had a bad coil or a rocker arm was loose...
It was using oil...and ran low enough to make 1 rod lockup and break.

Ok, camshaft looks good. It was smoking. I pulled quite a bit of oil out of it when I drained it last night... quarter of a 2l bottle, The rockers were not terribly loose I did see some flex in the rockers on that side. I also had oil on tip of the good piston so it was blowing by or going through valves.. Not sure which. The clean plug has me perplexed though... I'd figure the plug would have been dirty as well if it was working as well...
