There is absolutely NOTHING wrong with LA engines. They are sturdy, reliable, user friendly engines. They are not powerhouses so while they are excellent for trainers they are not the engine choice for anyone wanting speed or acrobatics. I learned to fly glow with an OS .46LA. My father flies his LT-40 around with an OS .40LA. He flew his Scooter with an OS .10LA. All those engines ran great right out of the box. The thing about the LA series engines is that they dont have the power of a ball bearing engine such as the FX series. They are not meant to. Other than that, there is nothing wrong with them.
