My favorite engine
I bought my first .68 about 3 years ago. It was bought used from a friend who used it which had at several hundred flights on it and I now I have put an additional 122+ hours on it. It is now finally starting to show its age. I still am flying it on my midget mustang, it starts easily, is very reliable, the only change is that its down about 400 rpm off the top end.
It is the best engine I have ever owned. I can't say nothing but good things about it. I will glady buy another one or just rebuild this one. I wish all of my engines were this easy to own and operate.
