Happy to join and take in the knowledge of the collective group. My dad and I own a 1940 J3C-65 that has been in our family since the 50’s. I will be gathering some info on an engine overhaul / upgrade in the near future as we just had some valve/cylinder issues pop up. I’m looking to set us up for the next generation of family aviators as my youngest (17) is working on his license currently. Thanks and greetings from northern Michigan.
