I have got say, I am disappointed. I have 4 Sachs based engines, three 3.2. and a 4.2. One of them is a Fox, and to hear they have discontinued them is not good news, they did a nice job on the engine and it has run flawlessly, as have the others. Must be as long as Bill Jenkins has parts though, I'll probably never have need to replace them with the other brands. From what I have seen, they are as good or better than many in their class, and some bigger than their class.
