Considering an engine upgrade for the Champ I have come across an ad on Barnstormers for an engine mount. The ad says the mount is for an A65/75 or C85 but not for C90 or O-200.
Can anyone enlighten me as to what the difference might be between a mount for an A65 and an O-200?
Everything about your Aeronca, not Chief or Champ or Sedan specific.
