quote Buccaneer:

Should I just throw the whole power head in a bucket of solvent and try again next year?
I don’t want to do too much prying on the aluminum surfaces.
Thanks for any suggestions!

I ended up filling the cylinders with transmission fluid and got them freed up fairly quickly. Maybe two or three months total?
Used a little bit of heat as I had access to the cylinder walls because I took the walls off, as I said I don’t believe that was a huge help, probably helped get the fluid down into the piston rings somewhat.

It sounds like you took the crank case apart? If so, I’d recommend trying to get it back together, I was able to use a breaker bar on the crank to get it to spin and without that I don’t think I would have gotten mine free.
