"No one has answered your question of whether it is safe to turn the engine over (by hand, I assume) for the purpose of inspecting various parts."
Don't if you want to salvage this engine. It may be a good engine for your project, but now needs special attention.
The answer is there. One you can't do a compression test that is worth anything because of the long dry spell and the engine should be run before a compression test. The lack of oil seals and other problems it would cause would be counter productive for you. If you start turning the engine over by hand after such a long dry spell you are likely to cause scrapes and scratches on dry metal parts that just applying oil in a cylinder can't reach, especially the bearings and journal surfaces. The best thing would be to have someone that knows a Rotax to just pull the heads and take a look or use your borescope you have and just pull the plugs and take a look without rotating the prop. The person that left this engine sit for 12+ years did it no favors. This is different than an engine shipped from the factory that sits a few months. It was all pre-lubed at assembly and then run at the factory so when the new owner does their oil purge and starts it the first time it isn't dry anywhere nor does it have any bad "O" rings which may leak and cause damage. The "O" rings and leaks alone here make starting this engine risky and the dry parts will certainly cause damage at the first turn of the key.
Give Rob a quick call and just talk to them.
