Don't know about the stuff rear of the clutch on that model,

but the engine looks like an easy one.

Like said, the rusty plug cylinder is where a problem is.

make sure the valves are not stuck.

if some are, pull the rocker shaft to take that out of the equation.

blow out that cylinder or reduce a shopvac hose until you

can get it in the sparkplug hole.

You have to get any water out first or your solvent

will just float and won't do anything.

Then soak em all for a few days with your favorite solvent.

You can then pry on the flywheel gear, or in a normal situation

rock it in high gear (sounds like not an option for you)

I don't have much luck with that, I put a oak stud on my floorjack

and gently put some upward pressure on a rodcap/crank throw.

usually works

smaller, lighter tractors with very stuck engines, I jack the throw until

the front wheel is light. When I come into the shop

and the wheel is on the ground, it's loose.

at the first sign of movement, switch from solvent to lots of oil

before turning it over

good luck

EDIT: just had to add after seeing eltoro's same time post, that when all else fails, fire works. very stuck 123 that I just freed resisted everything until I set it on fire :D After burning, jack on a throw going up, pounding on a piston that was going down freed it
