Ah, memories. I remember playing with a spare R-680 Lycoming Engine Dad had in the shop when I was about 5. I use to pull the rocker covers off and put them on again keeping myself busy. Today, Liam our 2 year old came to the shop to visit. We handed him a 7/16 open end wrench and he went right for the rocker cover fasteners on a Jacobs R-755 engine so, does it warm the heart to know he's like Dad, Uncle and Grandpa or confirm that he's going to be diagnosed with airplane craziness? We'll see but, I suspect he just might end up liking airplanes.
