I have many hours on EA-81, also one overhaul and everything is working well. It was working well also with original Hitachi carb., but I decided for Weber, because of better parts availability. And now I'm satisfied. Injection will be better, I know, but I'm not in the USA, but in Europe, so it will be expensive for me. And I don't like many electric features around engine, so carb. is good for me. Power and reliability is sufficient.
