Good Job!!! Hopefully Ken will be by with your RCU ATTABOY!! I have heard some people have great luck with their LA engines. I guess I was one of the unlucky ones. Just seemed like they were underpowered to me, I still have them, maybe I will seal up the back plate, carb and head like somebody mentioned and put them on a smaller plane. Maybe that will restore my faith in the LA line. I love OS engines.
