OK, so I have another question that I'm sure has been answered before, but what's the best way to go about cleaning these gasket surfaces?
I tried a little last night with a rag and some denatured alcohol, but that didn't work too well. There's even some old gasket material still stuck on a few spots. Because it's aluminum and because it's the engine, I don't want to try to scrape it with a razor blade. I do have some rolls of emory cloth but, I don't want to go too far with that stuff either.
Is #0000 steel wool a good idea? Or maybe brake cleaner or degreaser and a soft toothbrush and a rag once I get the big stuff off?
I considered brass and nylon brushes (both of which I have), but wasn't sure if stuff wanted to be stubborn.
Like ealier, I was using my thumbnail to try to pick some stuck gasket off where I pulled the lifter blocks and it didn't want to come up, and my thumbnail is pretty thick and sturdy. I might could carefully pry it with an awl.
Luckily, for the most part, the gasket surfaces are already pretty clean like, where the cylinder base gasket goes and stuff.
This is clean enough, right (front cylinder, nose cone half)? There's no gasket material left, I can even see and feel the grooves from the original machining. I just can't seem to get the rest to come out. It's like a stain or discoloration. If you zoom on the close-up, even you can see the grooves in the picture.
Or does it need to be shiny clean? That discoloration doesn't feel like some kind of residue, and nothing I hit it with seems to want to get it off.
