Piston... MIA
The guys over on the Forum where I spend most of my time had never seen anything quite like this. I thought you'd want to take a look, too. The coolant is from removing the head, not contributing to the catastrophe
I had a leaking needle valve, took the middle carb off, replaced the valve, started the engine;new valve also leaked and flooded the carb; I killed the engine.
I then pulled the fuel line off the middle carb, shot the needle valve with carb cleaner thru the inlet nipple
and restarted the engine.
Within a couple seconds I heard an awful rattle and the engine died.
I restarted, no rattling but running poorly so I shut it down. The noise, the rattling reminded me of a chain saw loosing it's chain.
My thought shifted to the timing chain. I checked the cam timing by comparing the valve lash with the damper marks... Not a problem, so I pulled out the Compression Gauge.
Spark plug #6 looked like this
As to what exactly happened..so far it's all speculation. And I guess really doesn't matter at this point.
Lucky in a way that I have an original, used but un machined, short block to work with.
