The skinny: '68 or '69 Remington 754G (civilian). As far as I know, was in good working order when stored sometime in the mid-80s. The spark plug was robbed, and mud wasps filled the top of the cylinder with egg casings, as well as the exhaust ports (accessed via spark arrestor). I disassembled the saw completely save for the piston/rod in the cylinder. I carefully chipped the mud and dead spiders out of the exhaust ports and alternated blasts of compressed air and carb cleaner through the spark plug hole. I left it sitting in a vise with automatic transmission fluid sitting pooled in the exhaust ports and in the top of the cylinder. Over a period of 24 hours most of the fluid in 2 of the exhaust ports leaked down inside the cylinder but the top of the cylinder was still full. There doesn't appear to be any corrosion on the inside of the cylinder walls. I was going to try a mix of ATF and acetone, but this is as far as I've got. I can't get the piston to move just by pulling down on the rod by hand. Obviously trying to avoid breaking the rings, and I doubt there's a magic answer beyond what I'm already doing, but does anyone have any advice? Maybe just some moral support? Being patient with it is the trickiest part.
