The O.S LA is getting a pretty bad rap on here by some, but from my experience of owning one I just can't see this as the worst engine. Sure maybe a TT GP 42 might be a little better buy for the money for this engine type and class, but I don't don't believe that the LA's are that bad if used for the right application. Mine runs like a champ! Its not a real powerhouse, but it has been dependable. It hasn't cost me a Plane yet due to a deadstick, so that has to count for something in my eyes. The only issue I could believe about this engine is an issue of cost, but other than that I can't see to much bad in one of these engines. Just about all O.S engines are a tad overpriced in my book, but generally they have a pretty good rep and can afford to be a bit higher in price because of demand. Please correct me if I am wrong, but I just don't see the LA as an engine to avoid at all cost!
