I was looking through my work shop and came across an engine that I didn't even know I had!! It is an OS 40LA that I bought a few years ago and TOTALLY forgot about!!! It is new in the box and has never been run. Well, I guess I'll just have to use it in my new Cub!! Thanks again to all who replied with all your suggestions!! If I hadn't found this one, I was leaning toward the 46LA. This worked out pretty good after all!!!!
