You have any thoughts on what I'm lookin at here. I've never heard of cooking an engine submerged in coolant before. I'm willing to try it though. I did manage to get the prop and all other parts off the front and is still very tight.
Slow cooking in green engine coolant is the gunge-removing zeitgeist.
You could try an auto-factors for a gallon of general purpose solvent.
That is normally a mix of Alcohol, Xylene and Toluene that should have a good go at getting rid of that castor varnish.
Even a week-long immersion in glow-fuel might loosen things up for you.
