Two thumbs up Hobbsy. I never met any Fox engine that I couldn't get to run better than or outlast an OS

I own Fox engines as old as 45 years old and they still run flawlessly.
I agree. I recently lost almost all of my engines in a fire, but of the couple hundred of them among the best were Foxes. I had OS FSR, FP, and LA 15s, but the Fox BB 15 was easily the best. Good enough that I bought three of them. I have always thought that OS engines were hard to beat for being user friendly, but the Fox 74 I purchased a couple of years ago was as easy to run as anything I had. (possible exception being my old OS 1.08 FSR which, fortunately was stored separately from the other stuff).
