I am coming into a Kitfox II my grandfather built in '88. It has a Rotax 532 with only 50 hours on it but it has been in storage for almost twenty years. Would it be worth it to try to get the engine running again or just get a new 582? I am not very mechanically inclined and will have to pay someone to do all the work. One mechanic told me he wasn't sure if he could even get parts for a 532 and I don't know if I need a new gearbox too.

What would be my best option for this plane?
