Took the head off and looked things over - needs CLEANING BAD before I go any further - here you go: https://youtu.be/feniPslUUfQ

My point is I cannot do video period I'm on dial up and to try to do a video would take the whole days
 
Get the liquid out and dry to see what it looks like from the top of the piston up. With that much liquid on top the rings might be holding the liquid up rather than rust. Most of the valves look as though they could be salvaged. The rusted in valves for sure will need new seats installed. I have had a lot worse looking engines that I rebuilt. You will need to look close to the sleeves before deciding they could be used.
 
Thanks much .. Gary

Like Dick said clean out the cylinder and clean it up real good,soak it with a good penetrating oil for awhile then cut your self a round piece of some hard wood like Dogwood just smaller than the sleeve.Smartly tap the piston a couple times and give the oil time to work on the rings sooner or later it'll probably come loose and you may loosen any stuck rings.On the head I'd send it off to a machine shop to
clean it and do the valves,might clean right up or the valve stems my be pitted and they'd break sooner or later so you need to replace them.You want the valves working in top order because if you drop a valve you got major problems and $$$$ problems another reason I always like to pull the head on a stuck engine. Ounce of prevention is worth a pound of cure is never more true
than dealing with something like this.
 
The best success I've had in getting a seized piston loose...take a steel cup from a brake caliper, place it on top the piston and hit it with an air chisel full blast while you have penetrating oil generously around the bore. Once you see it move some do it to a piston that you know is moving in the opposite direction. After the "bad" piston moves down a bit use fine grit paper (400 is good) and smooth off the rust ring before moving the piston and rings up and past that point. You soon get the idea once you have a bit of movement. I have done several engines this way that became good runners.
 
Just went through the exact same thing with my B. Had to replace two seats. I opted to replace all the valves cause it was cheap and easy. More than two of the old valves were pitted real bad. All the guides were good. As far as my stuck piston was concerned I couldn't get it unstuck and it looked far better than what you have. I just unbolted the rods and used a piece of oak and tapped the piston sleeves out and honed them and put new rings in. Good luck.
 
I got it to turn ... by using the flywheel gear (removing the starter) ...

It turn about an INCH !! but it turned!!

Now waiting and soaking ... can't turn it yet with the crank or back wheel jacked up in 3rd gear ..

Hoping I will remain .. PATIENT . ha !!

Thanks

Ooooooops ..... well I turned the "crank wheel/pulley on the front of the tractor - I am assuming it is at the end of the crank" ..

So .. I will resort to ---- probably -- pulling it or pushing it back and forth ---

I hate to put a pipe wrench on the end of the crank - .. but would I hurt it?
I actually broke it loose with the flywheel gear ... may have to go back to that style ..

Any ideas would help - thanks

Gary
