There is a plane in my neighborhood for sale with the following engine:

Subaru NSI-E81 Engine 100HP with NSI re-drive

Is this a good engine? How long between overhauls?

I've been in the market for a LSA for a while now, still looking for something that agrees with me. Came close to a couple Aeronca's, but the deal didn't work out. Figured I should expand my horizons:

The plane is a Kitfox 4 in Massillon, Ohio on Barnstormers.
