The Valve Shadows are all black, nothing indented into the pistons. Thanks for letting me know it's a normal thing.
I drained the oil, that was not a pretty sight, and there is about 3/8" worth of sludge on the bottom of the sump, so of course that is getting a good clean out. How does the front oil drain pipe get mounted? I pulled it out so I could clean the screen, and it was totally plugged. I figure that's why I wasn't getting any oil pressure. I thought there would be a big nut like on the outside, but in the sump, but I don't see one.
I am having a lot of fun. I really like doing this sort of thing. If not Generators, it's old outboards. or old boats, or new boats, or building at my Swamp Camp. I figure if I stop I will just get old. I am 53 now, so there are a lot of projects in front of me...LOL
