I just picked up a '39 1/2 Ton that's been sitting for many years. The engine is free, thankfully, but I noticed I had one stuck valve. I assume it was just stuck in the position it had been sitting in. I pried it up by the spring with a screwdriver then rotated the engine hoping it would go down alright and then pop back up. It took doing this many times to get it loose and it now goes up and down on its own just fine, except for the fact that it only opens about 90% or so. My plan is to keep prying it up the rest of the way and hoping that the consistent back and forth movement will free it up so that it's as good as new. My other thought is that I can get a battery hooked up and keep cranking the engine and that with the consistent up and down movement it will hopefully loosen little by little until it's 100%. Any other suggestions or concerns, though? I've been spraying Blaster on it each time I move it.
Thanks.
Dan
