Well, I started the disassembly, it's not as bad as I thought.

Sams picures definitely looked worse. Mostly oil soaked and dirt. I don't see any grass in there. Definitely needs a mag end seal. I don't think the wetness down from the crank transferred up to the top by the governor seal. So I think I probably can get by with just gaskets and seals being replaced and not have to crack her open and replace head gaskets, valve seals, etc. Or, if I'm this far in and have the parts should I just do it?
