Hello All, I'm and A&P with lycoming experience, and a flying RV7. I am new to the rotax world. I'm looking to purchase a 1991 kitfox model 3. It has a very early rotax 912 that has not been overhauled since new that I am are of. The plane has been sitting since about 2015, and has about 460 hours total time on it. I know that opinions will range from "run it as long as the compression and oil analysis look good" to "don't even think about touching it until its been overhauled. For what its worth the engine has perfect compression and a bore scope of the cylinders look good. I know this isn't the whole story though. What specific things would you be concerned with on an engine of this age? Crank? cam? gearbox? case fretting?

Given the idea of an overhaul, do any of the parts from an engine of this vintage have any core value?
The engine SN is 379(2?)738
Thanks in advance

Caleb
