A little more progress today after rearranging some stuff in the garage to get a bit more working room, then doing some shopping with the wife.
Picked up some more carb cleaner and some engine degreaser at O'reilly on the way home. The degreaser works a lot better than the foaming cleaner that I had tried before. Doesn't smell too bad, either. Opened the garage door and ran the box fan to move some fumes out. Still a little crud left on the bottom in corners, but I'll get it tomorrow.
Right side is starting to clean up nice. The front must have been off and painted - the cleaner takes the paint off of it quickly. The back covers are still pretty bad, and I still need to clean around a lot of bolts. Thinking maybe take them out one at a time, clean under, clean the bolt head, re-torque.
I pulled the right side T cover from the transmission and will probably polish it. I think that all parts and the paint are in.
Cleaned and weighed the valves today. The last three new intake valves are about 3 grams heavier that the one that I bought a couple years ago, but I don't think it will effect things as this is not intended for performance. These new valves (made in Japan) look a lot like they may be two-piece instead of coated seat. I'll have to check with a magnet tomorrow.
Sequence I'm using is engine degreaser, then carb cleaner, then 91% isopropyl alcohol. Using nylon, brass, and SS bristle bushes and Scotch Brite pads with a screwdriver to shove the scrubber into slots and such, and finishing up with a cotton rag then I'll do final wipe down with isopropyl and paper towels.
Will probably paint the bottom fins first with it hanging and let it cure for four or five days. Then set it down on the carpeted furniture dolly and paint the rest.
