The full pressure 235 is a great engine.
As far as cleaning goes, you might think about laying down a couple of layers of plastic, and then get a big tub you can put under the engine to catch the gunk. Scrape off what muck you can with a putty knife.
Buy a few cans of heavy duty oven cleaner and spray the engine down. Follow the directions.
Then spray the engine down with a good heavy duty degreaser. Let it sit for a while, and then spray it down with a squirt bottle full of water. Repeat, wipe, scrap and clean. Finish up with something like a brake cleaner. Wear goggles. Keep up with your ventilation and think about wearing a respirator.
I have cleaned a couple of tractors this way in my garage. You will probably lose some or all of the paint on your engine in this process.
Good luck, send pictures! Can't wait to hear how she runs with the new engine.
