You could also pull carbs and exh manifolds, use air nozzle to blow 
oil/atf into those.

To break it loose, a big screwdriver/prybar between flywheel/ring gear 
teeth and bellhousing/starter nose.
That will bet you enough leverage to un-stick it.
Then you rock it back and forth with ring gear then use the bolt on the 
I say 'rock it' because that lets some of the crud that you're scraping 
off the cyl walls to get out of there and fresh oil to get it.
But if it doesn't free up pretty quick after breaking it loose, then it 
needs to get torn down anyway.

I wouldn't expect that air pressure on the piston would do the job of 
breaking it loose, but - eh,  you could try.
The adapters they make for compression testers, maybe? Just a rubber tip 
thingie could work.
I took an old spark plug once, broke the porcelain out of it, and welded 
some kind of fitting to it.
