I did the crock pot/antifreeze method. I am totally impressed. This engine was used and had a good buildup of caster. I let it set in the crock pot for about 12 hours in the garage and it looked like new afterwards. I did not take the engine apart. I did remove the carb and seal and set the engine on it's head. That was the part that was the worst. I did not cover the entire engine as only the top of the engine needed cleaned. The only other difference was I used a Potpourri pot. Basically a small crock pot. It was just big enough fit my .46 in nicly. This way I did not have to use a lot of antifreeze.
