Guys,
I've posted Dave Good's video clip of the first engine run on the 239 that he rebuilt for my Lynx. While I might be a bit biased, it is one sweet sounding engine.
If for some reason this link
https://youtu.be/mpHUWWWILVI, does not work, a search on You Tube for "1944 Lynx" will lead you to it.
