WIC, I did do the 2nd leakdown test. Or, at least I tried. Basically, air shot up through the carburetor. I'm pretty sure something there got damaged as a result. When I tried to run the engine after the 2nd test it smoked a million times worse and ran like crap. It was all very disheartening. I've considered using the Berryman cleaner to see if a ring would loosen up. My concern with that is the sludge in the oil pan. I don't want to dissolve enough of that to clog up oil passages. I've considered removing the cylinder head, but that will require draining oil and coolant. Basically, I'm encountering inertia, due to the amount of work and risk each option carries. That is why I was looking for a running engine to just drop in. Not sure which way to turn at this point, so I've been doing fall lawn and garden tasks instead....
