Windshield washer fluid in the mix canister.

Pretty damn close I'd say.

Nope, the bearings are perfect.

Signs of detonation, I am sticking with acid rain...

 

[jockeydeuce]

I've seen it lots too......I suspect it's water in the fuel, but only a guess.....Water has explosive expansion.

I'm just calling it "bad gas" Rob.

 

[VINIFIREWOOD]

back in the 80's, in a car they called it "ping"

 

[ELECT6845]

Ignition advanced and ran on high octane fuel, carb tuned wrong, leaned out and went boom?????? just a guess

Funny. I just tore down a MS211 that had a piston and cylinder just like that. The scoring was not as bad on the piston but it was full of divets.

[dieselfitter]

[rdtreewalker]

Water in the gas

 

[skanj0]

Water from a Ethanol fuels

Steam. surprised to see it here. Pretty common with blown head gaskets leaking AF in something like an auto/ truck engine. Corn is for cows...n stuff.

I'm still figuring out how you get your camera to take such good close-up pictures.

BTW......I'm with the bad gas explanation.
