Mills 75 Diesel Model Aircraft Engine - Second Run in 50 Years

After the first run we filmed the second run. The engine had really loosened up and in an attempt to get it to fire the correct way a flick and firing backwards , then a correct rotation flick did the trick. I don't know why this works but it always does. Mostly does. It must clear fuel from the transfer ports or something. Once the engine cleared its throat with fresh prime of fuel ( because now its hot from the first run) . It went. Of course knocking back the compression a 1/4 turn also can help when the engine is hot. Once its going turn the compression back up. This could go better yet. It needs a tweak or two. Its running well considering what it looked like a week ago. Thanks for watching Steve
